Samsung will ship 1, 2, 4 and 8GB MMC memory cards later this year, the South Korean giant pledged today. It claimed they will not only be the biggest capacity MMCs on the market. Others in the line-up will offer the fastest data transfers, it said.

 

 

Branded MMCplus, the cards build on Samsung's existing MMCplus range, which currently runs at up to 1GB. The company said will also ship faster versions under the Mach MMCplus label. The fast cards have a read-speed to 40MBps and a write-speed of 25MBps, Samsung claimed. The cards are based on the MMC System Specification version 4.1, which can support speeds of up to 52MBps, according to the Multimedia Card Association. Samsung said it will offer two Mach cards: a 1GB part and a 2GB part. ®

The xD-Picture Card is a type of flash memory memory card, used mainly in digital cameras. xD stands for extreme Digital. The cards were introduced into the market in July 2002 and developed by Olympus and Fujifilm. Toshiba Corporation and Samsung Electronics manufacture the cards for Olympus and Fujifilm. Other brands, including Kodak, SanDisk, and Lexar, now sell xD cards.

Card specifications

xD cards are used in Olympus, and Fujifilm digital cameras and Olympus digital voice recorders; Fujifilm also made an MP3 player that used the cards.[1] As of 2006 xD cards are available in these capacities: 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB, 1 GB, and 2 GB. An xD card is 20 mm × 25 mm × 1.78 mm and weighs 2.8 grams.

Type M and Type H cards

The original XD cards were available in 16 MB—512 MB capacities. The Type M card, released in February 2005 [2], uses Multi Level Cell (MLC) architecture to achieve a theoretical storage capacity of up to 8 GB. As of August 2006, Type M cards are available in sizes from 256 MB to 2 GB. However, the Type M suffers slower read-write speeds than the original cards. The Type H card, first released in November 2005 [3], offers higher data rates than Type M cards (theoretically as much as 3 times faster).[4] As of 2006, Type H cards are only available in 256MB, 512 MB and 1 GB capacities. Olympus xD cards, include special “picture effects”, although most of these are only available in use with Olympus digital cameras. Due to changes in the cards' storage architecture, newer Type M and H cards may suffer compatibility issues with some older cameras (especially video recording). Compatibility lists are available for Olympus (PDF format) and Fujifilm. The newer cards are also incompatible with some card readers.

The MultiMediaCard Association (MMCA) is the open standard memory card organization, promoting worldwide adoption of storage media and peripheral I/O devices designed especially for mobile phones and digital imaging devices. It enables a myriad of applications to come together and share digital media contents.

The MMCA oversees standardization activities for removable storage media, including MMCplus™, MMCmobile™ and MMCmicro™ Cards; SecureMMC; ATA on MMC; Multiple Interface Cards; and MMC I/O.

MMCplus™, MMCmobile™ and MMCmicro™ Cards, built to the latest MMC standards v4.2, offer wider bandwidths and the highest data transfer rates among memory cards available in the market today.

Founded in 1998, the MMCA provides a global forum for memory card and semiconductor component suppliers, software vendors and manufacturers of mobile electronic devices who jointly endorse and promote the worldwide adoption of MultiMediaCards and the MMC standards.

MMCA Principles:

• The organization is dedicated to open industry standards
• These standards are established consensually, with the equal participation of MMCA members
• Product interoperability and compliance are integral to the specifications and standards.

The MultiMediaCard (MMC) is a flash memory memory card standard. Unveiled in 1997 by Siemens AG and SanDisk, it is based on Toshiba's NAND-based flash memory, and is therefore much smaller than earlier systems based on Intel NOR-based memory such as CompactFlash. MMC is about the size of a postage stamp: 24 mm x 32 mm x 1.5 mm. MMC originally used a 1-bit serial interface, but newer versions of the specification allow transfers of 4 or sometimes even 8 bits at a time. They have been more or less superseded by Secure Digital cards, but still see significant use because MMC cards can be used in any device which supports SD cards.

Typically, an MMC card is used as storage media for a portable device, in a form that can easily be removed for access by a PC. For example, a digital camera would use an MMC card for storing image files. With an MMC reader (typically a small box that connects via USB or some other serial connection, although some can be found integrated into the computer itself), a user could copy the pictures taken with the digital camera off to his or her computer. Modern computers, both laptops and desktops, often have SD slots, which can read MMC cards.

MMC cards are currently available in sizes up to and including 8 GB, and are used in almost every context in which memory cards are used, like cellular phones, digital audio players, digital cameras and PDAs. Since the introduction of Secure Digital card few companies build MMC slots into their devices, but the slightly thinner, pin-compatible MMC cards can be used in almost any device that supports SD cards. An exception is some mobile devices like the Nokia 9300 communicator, where the smaller size of the MMC card is a benefit.
