Memory Cards Complete Guide
Ever wondered what are these tiny chips? Confused by the name?
We are here to help you.
This article is about the various memory components 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 generally used to describe the whole family of Memory Sticks. This family includes the Memory Stick Pro,Revision allows greater maximum storage capacity and faster file transfer speeds, and Memory Stick Duo, a small form-factor version of Memory Stick.

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 demand from Sony for a smaller flash memory card for pocket-size digital cameras and mobile phones, as well asSony PSP. Memory Stick Duos are available in all variants, the same as their larger cousins (normal to the available limited to 128 MB, larger Pro Sticks, with and without high-speed mode, with and without MagicGate support) and a simple adapter (often together with the sale of Memory Stick Duo), a duo can to every device that can accept its larger cousins may be used.
Memory Stick Micro M2
15.0 × 12.5 × 1.2 mm
In a joint venture with SanDisk, Sony announced a new MemoryStick format on 30 September 2005. The new Memory Stick M2 ( "micro") measures 15 × 12.5 × 1.2 mm and could theoretically be 32 GB in the future. Maximum speed is 160 Mb / s. It will come with an adapter, much like the Duo Sticks, to ensure compatibility with current Pro devices.
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 this point theMMC card was the smallest memory card about the size of a postage stamp on the market based on flash memory technology. The card is very similar to the Secure Digital Memory Card, actually the SD card is inserted into place on the MMC card. They have almost the same form factor is the only difference is that SD cards are slightly thicker and they have a write-protect switch.
As the MMC card is too slow transmission speed, 2.5 Mbps, compared to other memory cards, especiallyon SD Memory Card, a new high performance version of the MMC card was compared in 2005, introduced under the name MMCplus. The MMCplus today has the highest, up to 52 MB / sec, theoretical data transfer speed in the whole memory card industry.
The MultiMediaCard Association announced that by the end of 2005 the SecureMMC apply only to the MMCplus and MMCmobile memory cards available. The SecureMMC is a copyright protection application that features DRM, Digital Rights Management,and VPN, Virtual Private Network capabilities.
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, about half in size, and was specificallyare 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, dual voltage (DV) RS-MMC was introduced. It is basically the same card as the standard RS-MMC but operates with dual voltage, 1.8 V and 3.3 V, resulting in lower energy consumption, contributing to longer battery life for the life of host devices. The DV RS-MMC and RS-MMC areoperate totally compatible, but for some phones, especially Nokia, with only 1.8V cards the regular RS-MMC will not work. We recommend that you always have the Dual Voltage RS-MMC buy for sure that your memory will work with the electronic device.
MMCmicro Card
MMCmicro
12 × 14 × 1.1 mm
The introduced MMCmicro, formerly known as S-CARD from Samsung, was adopted and introduced in 2005 by the MultiMediaCardAssociation (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 is among the smallest in the world. It was specifically used in mobile phones and other small portable devices.
The MMCmicro card is an adapter, MMCplus available. This not only makes it compatible with all MMC and MMCplus slots but also to all SD Memory Card slots. It isimportant to note that music files to MultiMedia Cards, I do not play in a position to return to when they are in an SD memory card slot due to the copyright protection features of the inserted SD slots supported.
Since the MMCmicro is the latest card to develop and to market it is not compatible handsets and introduced to many electronic devices still. However, it is expected that one of the memory card formats that dominate the mobile phone sector will be among the pioneersmicroSD in the development and the Memory Stick Micro.
Secure Digital Card
SD
32 × 24 × 2.1 mm
The SD Memory Card or Secure Digital was introduced in 2001, SanDisk Corporation, Matsushita (Panasonic) and Toshiba. The SD memory card on the MultiMediaCard, MMC memory card standard and has almost the same form factor, the size of a postage stamp, are the only difference that the SD card is slightly thicker and has aWrite-protect switch. Since MMC cards are thinner than SD cards can be used in all SD Memory Card slots are, but not vice versa.
The SD card is today the most commonly used memory card. It can be found in most digital cameras, PDAs and many other electronic devices. The SD Memory Card slots can be used for more than flash memory cards. The SDIO, Secure Digital In & Out, is the general term for the many expansion modules that can be found in the form of the SD memory cardFactor. SDIO modules can be inserted into the slot, and for other functions like Bluetooth adapters are used, GPS receivers, digital cameras, TV tuners, etc.
miniSD Card
miniSD
21.5 × 20 × 1.4 mm
The miniSD was introduced in 2003 by SanDisk Corporation in cooperation with Matsushita (Panasonic) and Toshiba. Later that year the miniSD format was developed by the SD Card Association as a second form factor memory card in the Secure Digital adaptedFamily. MiniSD is a smaller version of the SD Card format, expect about 60% smaller in volume and provides the same benefits as the SD Memory Card, the write-protect switch.
MiniSD was designed specifically to be used in small portable electronic devices like digital cameras and cell phones. But since all miniSD memory card always with an SD memory card adapter coming, they are compatible with all SD Memory Card slots, and thus the compatibility with the rapidly growingNumber of SD Memory Card compatible devices on the market.
MiniSD was the second after SD memory card adapted to memory card from the SD Card Association, which today consists of three members will be. In 2005, the microSD was introduced as a third, and smallest, member of the Secure Digital family.
microSD Card also known as Transflash
μSD
11 × 15 × 1 mm
rashFlash, formerly known as T-Flash, was developed by SanDisk Corporation in 2004 introducedworld's smallest memory card, about the size of a fingernail. TransFlash was specifically used in mobile phones. Motorola was the first mobile phone manufacturer to adapt the TransFlash memory card standard.
In the 3rd Quarter of 2005 TransFlash of the SD Card Association as the third form factor memory card in the Secure Digital family has been adjusted after SD Memory Card and miniSD. After the adoption, name changes TransFlash microSD. The microSD has exactlythe same dimensions and specifications as the TransFlash and therefore both memory cards are fully compatible with each other.
Today the microSD is the most commonly used memory card in mobile phones and the SD Card Association's aim is to provide a microSD memory card de-facto standard for all phones. All TransFlash and microSD cards always come with an SD memory card adapter, which makes them compatible with all SD Memory Card slots. The microSD is about 10% in size comparedon the memory card and about 30% compared to SD, miniSD.
xD-Picture Card
xD
20 × 25 × 1.7 mm
The xD-Picture Card was introduced in 2002 by Olympus and Fuji film as a replacement for the older SmartMedia card. It is manufactured exclusively by Toshiba and is only a brand name products under the name of Fuji Film and Olympus.
The xD-Picture Card format was designed to be used in digital cameras and is more or less only used in Fuji Film andOlympus digital cameras. How not accept SmartMedia Card, xD-Picture Card, a controller chip, which can make it into a small form factor, but at the same time, it can reliably to the host controller chip device.
