The Executive Summary about Digital Memory Cards by Varun Krishnan

Digital Memory Cards

This article is about the various memory components available in the market for mobile phones.

Memory Stick

MS Memory Stick is a removable flash memory card format, launched by Sony in October 1998, and is also used in general to describe the whole family of Memory Sticks. This family includes the Memory Stick Pro, a revision that allows greater maximum storage capacity and faster file transfer speeds, and Memory Stick Duo, a small-form-factor version of the Memory Stick.

50.0 × 21.5 × 2.8 mm

Memory Stick Duo

MS Duo

31.0 × 20.0 × 1.6 mm

The Memory Stick Duo, which is slightly smaller than the competing Secure Digital format, was developed in response to Sony’s need for a smaller flash memory card for pocket-sized digital cameras and cell phones, as well as Sony’s PSP. Memory Stick Duos are available in all the same variants as their larger cousins (normal ones limited to 128 MB, larger Pro Sticks, with and without High Speed mode, with and without MagicGate support), and a simple adapter (often sold along with the Memory Stick Duo) allows a Duo to be used in any device that can accept their larger cousins.

Memory Stick Micro M2

15.0 × 12.5 × 1.2 mm

In a joint venture with SanDisk, Sony announced a new Memory Stick format on 30 September 2005. Multi Media Card

MMC

32 × 24 × 1.5 mm

The MMC card or MultiMediaCard was introduced in 1997 by SanDisk Corporation and Siemens AG. At that point the MMC card was the smallest memory card, about the size of a postage stamp, in the market based on flash memory technology. The MMC card is very similar to the Secure Digital Memory Card, actually the SD Memory Card is based on the MMC card. Since the MMC card had slow transfer speed, 2.5 MB/sec, in comparison to other memory cards, mostly compared to SD Memory Card, a new high performance version of the MMC card was introduced in 2005 by the name MMCplus. The MMCplus has today the highest, up to 52 MB/sec, theoretical data transfer speed in the whole memory card industry.

Reduced Size Multi Media Card

RS-MMC

16 × 24 × 1.5 mm

MMCmobile (RS-MMC)

RS-MMC, Reduced Size MultiMediaCard, was introduced in 2003 by the MultiMediaCard Association (MMCA) as the second form factor memory card in the MultiMediaCard family. The RS-MMC is a smaller version of the standard MMC card, approximately half in size, and was specifically designed to be used by mobile phones and other small portable devices.

Dual Voltage Reduced Size Multi Media Card

DV RS-MMC

16 × 24 × 1.5 mm

In 2005 the Dual Voltage (DV) RS-MMC was introduced. The DV RS-MMC and the RS-MMC are completely compatible with each other but since some mobile phones, mostly from Nokia, only operate with 1.8V cards the regular RS-MMC will not work. We recommend to always buy the Dual Voltage RS-MMC for being sure your memory card will function with the electronic device.

MMCmicro Card

MMCmicro

12 × 14 × 1.1 mm

The MMCmicro, formerly known as S-CARD introduced by Samsung, was adopted and introduced in 2005 by the MultiMediaCard Association (MMCA) as the third form factor memory card in the MultiMediaCard family. MMCmicro is the smallest, about the size of a fingernail, memory card in the MultiMediaCard family and among the smallest in the world. The MMCmicro memory card is available with an adaptor, MMCplus. This makes it not only compatible to all MMC and MMCplus slots but also to all SD Memory Card slots. Since the MMCmicro is the latest memory card to be developed and introduced to the market it is not that compatible to many mobile phones and electronic devices yet. Still it is expected to be one of the memory card formats that will dominate in the mobile phone industry among the frontrunner microSD and the under development Memory Stick Micro.

Secure Digital Card

32 × 24 × 2.1 mm

The SD Memory Card or Secure Digital was introduced in 2001 by SanDisk Corporation, Matsushita (Panasonic) and Toshiba. The SD Memory Card was based on the MultiMediaCard, MMC, memory card standard and has almost the same form factor, the size of a postage stamp, the only differences are that the SD memory card is slightly thicker and has a write protection switch. Since MMC cards are thinner than SD Memory Cards they can be used in all SD Memory Card slots but not vice versa.

The SD Memory Card is today the most common used memory card. The SD Memory Card slots can be used for more than flash memory cards. The SDIO, Secure Digital In & Out, is the general name for the many expansion modules that can be found in the SD Memory Card’s form factor. miniSD Card

miniSD

21.5 × 20 × 1.4 mm

Later in that year the miniSD format was adapted by the SD Card Association as the second form factor memory card in the Secure Digital family. MiniSD is a smaller version of the SD memory Card format, about 60% smaller in volume, and offers the same benefits as the SD Memory Card expect of the writing protection switch.

MiniSD was designed specifically to be used in small portable electronic devices like digital cameras and mobile phones. But since all miniSD memory cards always come with a SD Memory Card adaptor, they are compatible to all SD Memory Card slots and thereby provide compatibility with the rapidly growing number of SD Memory Card compatible devices in the market.

MiniSD was the second, after SD Memory Card, memory card to be adapted by the SD Card Association, which today consists of three members. microSD Card also known as Transflash

11 × 15 × 1 mm

Motorola was the first mobile phone manufacturer to adapt the TransFlash memory card standard.

In the 3rd quarter of 2005 TransFlash was adapted by the SD Card Association as the third form factor memory card in the Secure Digital family, after SD Memory Card and miniSD. After the adoption, TransFlash changed name to microSD. Today the microSD is the most common used memory card in mobile phones and the SD Card Association’s objective is to make microSD a de facto memory card standard for all mobile phones. All TransFlash and microSD cards always come with a SD Memory Card adaptor, which makes them compatible to all SD Memory Card slots. The microSD is about 10% in size compared to SD Memory Card and about 30% compared to miniSD.

xD-Picture Card

20 × 25 × 1.7 mm

The xD-Picture Card was introduced in 2002 by Fuji Film and Olympus as a replacement to the older SmartMedia Card. The xD-Picture Card format was developed to be used in digital cameras and is more or less only used in Fuji Film and Olympus digital cameras. Like SmartMedia Card, the xD-Picture Card does not incorporate a controller chip which allows it to have a small form factor but at the same time making it dependable to the host device’s controller chip.

Digital Camera Memory of Hi Def Video – Do You Really Need It?

The Best Summary about Memory Camera by Abraar Bashir

Memory Camera

And this would certainly be where video is headed, but that is not where most of us are with our digital cameras and their memory cards. In fact, most of us are still marveling over the 4GB, 8GB secure digital cards (nicknamed sdhc cards) that we have come to be familiar with. And if the sdhc cards are not catching our eye (which do allow us to have the 4GB and 8GB by the way) then it is likely we are using the M2 memory cards or the Micro-SD memory Cards. That’s for those of us who need or use digital camera memory.

People who need memory sticks – maybe for their printer, or computer, or one of their favorite gaming machine may not be using these types of memory cards, but you can bet if they want any type of ability to save any large files, they’ve got a memory card.

When expandable memory slots were first developed and incorporated into the portable digital devices we all know and love, it was hard to think with the idea that that latest and greatest gadget would ever need anything like more memory. There were thousands of people who thought that buying a memory stick was just some cool new sales ploy to get more money out of them. However, what they didn’t know was that these small portable devices will not hold much in their internal memory.

Thus the evolution of external memory was not a sales ploy but a truly bona fide need. Some people may remember how there were those who scoffed at the idea of external hard drives. The fact of the matter is, your digital camera just isn’t so great of a device if you don’t have digital camera memory. Your computer will potentially run out of hard drive space if you don’t get an external hard drive.

Digital Camera Memory – An Introduction

The Best Summary about Digital Camera Memory by Jakob Jelling

Digital Camera Memory

The digital camera is essentially a computer-based device, whose core is controlled by the computer. And as a result the photographs are stored in a location called memory. Now, this concept is or paramount importance in discussing digital camera. Strictly speaking, digital camera memory is where digital pictures are stored inside the camera. The digital camera memory is an essential and often a very neglected and overlooked section of equipments for digital photography and camera. There are many types of memory available for digital cameras, and it is a good practice to mull over what type of memory a camera uses before buying a digital camera. Knowledge of the digital camera memory is very essential for using such a camera and capturing photographs. The most common form of such memory is a memory card. Generally, digital cameras come available with low capacity memory cards, and it is a wise purchase to acquire higher capacity memory cards in order to budget for an additional card for later use.

With the increment of a camera mega pixel counts, it becomes essential to use higher capacity memory cards. Some of the small sized cards are for example the 64 megabyte cards and larger ones are like 1-gigabyte cards or combinations of megabyte cards.

Digital camera memory is available in many shapes and facade depending on the type of digital camera that is being used and even and the number of pictures that are required to be stored in the digital camera memory. These different types of memory are solely dependant upon the requirements of the digital camera, like for example a camera using compact flash type 1, requires the use of compact flash type 1 digital camera memory. Other examples of types of digital camera memory are Compact Flash Digital Camera Memory. Generally, the sizes of a digital camera memory are as follows, 64 MB, 128 MB, 256 MB, 512 MB, and 1 GIG. Again, the digital camera memory depends upon the file format used to store photographs upon and the compression used by the manufacturer when storing digital images into memory.

For higher resolution photographs, 512 megabyte and 1 gigabyte cards are also available. These are some of the guidelines for revealing the true facts about the different digital camera memories and their secrets.

How to Choose a Digital Camera Memory Card

The Best Summary about Memory Cards Camera by Kristine Knight

: Memory Card Camera

Selecting memory cards for digital cameras can be tough. The quality and number of images depends on the type and size of digital camera memory card you choose. Here are some guidelines to keep in mind when selecting a card to store your digital images.

Digital cameras store images on thin, stamp-size memory cards. Images are transferred to a computer via a cable or by removing the memory card and inserting it in a card reader that’s attached to a computer. In general, using a memory card reader will give faster downloads and is easy to use.

How large a digital camera memory card you need depends on how many megapixels your camera has and whether you’re shooting RAW or JPEG. RAW files can commonly be 10-20 megabytes in size, while high-quality JPEG images will typically run 1-4 megabytes (always use high-quality JPEG settings).

You need a high-capacity digital camera memory card to store a reasonable number of images. Cards are relatively inexpensive. Small cards, such as 512 MB, should be used only for low megapixel cameras and JPEG files. For most cameras, get at least 1 MB, and if you have a high-megapixel camera and are shooting RAW, look for the largest-capacity card you can afford.

While there are several types of memory cards on the market, most cameras are designed to use only one type, with a few having two card slots. You need to buy the right type of card for your camera. If it did come with a card, that card is likely way too small. Cards do have speed ratings that indicate how fast they can store and retrieve data, but only the high-end pro cameras can really support the fastest cards.

Digital Camera Memory Card Buying Guide

With a digital camera you no longer have to deal with having to load the film, and develop the film etc. The actual device that holds these images is called the memory card. To put it simply, the memory card is an electronic and much more convenient alternative to films used in traditional cameras. The unique advantage of the memory card is that it is reusable as images on the memory card can be deleted, unlike films that are not useable anymore once developed, and thus discarded. Memory cards also allow you to easily view your pictures by simply transferring the images from the memory card to the computer, whereas films have to undergo a special process to develop the images on the film.

With all these versatile and innovative benefits memory card provides, digital camera has boomed in popularity. The digital camera memory card market has been flooded with a wide range of memory card brands. There are various types of memory cards available in the market today, including Memory Stick, Memory Stick Pro media format, SmartMedia, XD Picture card, SD and MMC cards and the most time tested, CompactFlash.

Before deciding on your memory card, check which type of card is compatible with your brand of digital camera. For most digital cameras, your choice of memory card is likely to be limited to just one or two of the above-mentioned types. Consult the camera manual to learn about the compatibility.

Also, consider buying a memory card with higher capacity, so that you can store more images at a time.
