M2
Memory Stick Micro
Sony Corporation announced in September, 2005, that in cooperation with SanDisk Corporation will start the development of the third form factor memory card in the Memory Stick family, after Memory Stick PRO and Memory Stick PRO Duo. The new much smaller, among the smallest on the market, Memory Stick Micro will have about one-fourth the size of Memory Stick Duo. Memory Stick Micro or M2 will be introduced in the first half of 2006 and is aiming to be used mostly in mobile phones and ultra small portable devices.
The Memory Stick Micro will be based on the PRO platform, which is used by both Memory Stick PRO and Memory Stick PRO Duo cards, meaning that it will offer high storage capacity and high transfer speed in a much smaller physical format. The only difference from the PRO cards will be the fact of having lower operating voltage through being dual-voltage. This will meet the demand from the electronics manufactures for lower power consumption contributing to longer lasting battery life for mobile phones and other portable electronic devices.
Memory Stick Micro cards will come with a Memory Stick PRO adaptor making them compatible to all Memory Stick PRO slots.

MEMORY STICK PRO DUO
MEMORY STICK PRO DUO
Memory Stick PRO Duo
Memory Stick Duo was introduced in 2003 by Sony Corporation as the second form factor memory card in the Memory Stick family. It is a smaller alternative to the Memory Stick and was developed to be used in small portable electronic devices, mostly mobile phones. It has the size of a postage stamp and has about half the volume of a Memory Stick.
The limitations of the Memory Stick Duo in storage capacity, max 128 MB, and transfer speed, 2.45 MB/sec, contributed to the introduction of the Memory Stick PRO Duo, later in 2003. The PRO platform was developed jointly by Sony Corporation and SanDisk Corporation. It has the same physical format as the standard Memory Stick Duo but the PRO platform offers higher storage capacity and higher transfer speed.
The Memory Stick Duo can always be used in a Memory Stick PRO Duo slot and in most of the cases a PRO card can be used in a Memory Stick Duo slot. We recommend you to look in the product’s manual for finding out if a Memory Stick PRO Duo can be used in your product’s Memory Stick Duo slot. However you will not be able to make use of the higher transfer speed that the Memory Stick PRO Duo has to offer when using it on a standard Memory Stick Duo slot. In cases like that the PRO card will have the same transfer speed as a standard Memory Stick Duo.
All Memory Stick Duo and Memory Stick PRO Duo cards always come with a Memory Stick or a Memory Stick PRO adaptor making them compatible to all Memory Stick slots. The Memory Stick Duo and Memory Stick PRO Duo can be found branded only under the name of Sony, SanDisk and Lexar. The Memory Stick Duo and PRO are almost exclusively employed by Sony and SonyEricsson products, mostly by SonyEricsson’s mobile phones and Sony’s PlayStation Portable, PSP.
The write protection switch on the back side of the card is not a standard feature on all Memory Stick Duo and Memory Stick PRO Duo cards.

MICRO SD
microSD - TransFlash
TrashFlash, formerly known as T-Flash, was introduced by SanDisk Corporation in 2004 as the world’s smallest memory card, approximately the size of a fingernail. TransFlash (microSD) was specifically designed for being 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 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. The microSD has exactly the same dimensions and specifications as the TransFlash and therefore both memory cards are completely compatible to each other.
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 volume compared to SD Memory Card and about 30% compared to miniSD.

miniSD
The miniSD was introduced in 2003 by SanDisk Corporation in cooperation with Matsushita (Panasonic) and Toshiba. 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. In 2005 the microSD was introduced as the third, and smallest, member of the Secure Digital family.

SD Memory Card
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. It can be found in most digital cameras, PDAs and in 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 name for the many expansion modules that can be found in the SD Memory Card’s form factor. SDIO modules can be inserted in the slot and be used for other functions like Bluetooth adapters, GPS receivers, digital cameras, TV tuners, etc.
The SD Memory Card was the first memory card to be introduced in the Secure Digital family, which today consists of three members. In 2003 the miniSD format, 60 % smaller than the SD Memory Card, was introduced as the second member in the Secure Digital family. In 2005 the microSD was introduced as the third and the smallest member in the Secure Digital family. Since both miniSD and microSD come with an adaptor, they can be used in all SD Memory Card slots. Buy always the smaller format if you have electronic devices that support the SD Memory Card format and any other smaller format from the Secure Digital family.

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. They have almost the same form factor the only differences are that the SD Memory Cards are slightly thicker and they have a write protection switch.
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.
The MultiMediaCard Association announced that by the end of 2005 the secureMMC application will be available only for the MMCplus and MMCmobile memory cards. The secureMMC is a copyright protection application that features DRM, Digital Rights Management, and VPN, Virtual Private Network, capabilities.
Since the MMC cards are thinner they can be used in all SD Memory Card slots but not the vice versa. Based on that fact the MMC and MMCplus memory cards can be used in SD Memory Cards slots they are today the most compatible memory cards in the market. It is important to keep in mind that music stored on MMCplus or standard MMC cards my not be able to play back when inserted into a SD Memory Card slot due to the copyright protection features supported by the SD slots.
