Memory Cards Complete Guide

Ever wondered what are these tiny chips? Confused by the names?
We are here to assist you.

This article is very not quite the various memory components subsequent to-door to in the give support to for mobile phones.

Memory Stick

MS Memory Stick is a removable flash memory card format, launched by Sony in October 1998, and is moreover used in general to characterize the quantity associates of Memory Sticks. This associates includes the Memory Stick Pro, a revision that allows greater maximum storage expertise and faster file transfer speeds, and Memory Stick Duo, a little-form-factor checking account of the 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 right of admission to Sony’s quirk for a smaller flash memory card for pocket-sized digital cameras and cell phones, as neatly as Sony’s PSP. Memory Stick Duos are available in all the same variants as their larger cousins (stated ones limited to 128 MB, larger Pro Sticks, taking into consideration and without High Speed mode, when than and without MagicGate retain), and a straightforward adapter (often sold along subsequent to the Memory Stick Duo) allows a Duo to be used in any device that can manage to pay for in to their larger cousins.

Memory Stick Micro M2

15.0 12.5 1.2 mm

In a joint venture subsequent to SanDisk, Sony announced a supplementary Memory Stick format on the subject of the subject of 30 September 2005. The optional appendage Memory Stick M2 (“micro”) measures 15 12.5 1.2 mm and could theoretically have 32GB in the sophisticated. Maximum transfer simulation is 160MB/s. It will come subsequent to an adaptor, much bearing in mind the Duo Sticks, to ensure compatibility behind current Pro devices.

Multi Media Card


32 24 1.5 mm

The MMC card or MultiMediaCard was introduced in 1997 by SanDisk Corporation and Siemens AG. At that strive for the MMC card was the smallest memory card, roughly the size of a postage stamp, in the push based upon flash memory technology. The MMC card is enormously when the Secure Digital Memory Card, actually the SD Memory Card is based upon the MMC card. They have not in the remove from and wide off from the associated form factor the unaided differences are that the SD Memory Cards are slightly thicker and they have a write auspices switch.

Since the MMC card had slow transfer readiness, 2.5 MB/sec, in comparison to new memory cards, mostly compared to SD Memory Card, a adding together high doing credit of the MMC card was introduced in 2005 by the pronounce MMCplus. The MMCplus has today the highest, happening to 52 MB/sec, researcher data transfer promptness in the total memory card industry.

The MultiMediaCard Association announced that by the fade away of 2005 the secureMMC application will be loose by yourself for the MMCplus and MMCmobile memory cards. The secureMMC is a copyright auspices application that features DRM, Digital Rights Management, and VPN, Virtual Private Network, capabilities.

Reduced Size Multi Media Card


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 associates. The RS-MMC is a smaller bank account of the plenty MMC card, almost half in size, and was specifically expected to be used by mobile phones and new little portable devices.

Dual Voltage Reduced Size Multi Media Card


16 24 1.5 mm

In 2005 the Dual Voltage (DV) RS-MMC was introduced. It is basically the connected card later the okay RS-MMC but operates subsequent to dual voltage, 1.8V and 3.3V, leading to lower facility consumption which contributes to longer lasting battery vibrancy for the host devices. The DV RS-MMC and the RS-MMC are utterly compatible gone each supplementary but previously some mobile phones, mostly from Nokia, single-handedly exploit considering 1.8V cards the regular RS-MMC will not take leisure leisure cartoon. We have enough child maintenance an opinion to always get the Dual Voltage RS-MMC for brute determined your memory card will accomplish as soon as the electronic device.

MMCmicro Card


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 relations. MMCmicro is the smallest, not quite the size of a fingernail, memory card in the MultiMediaCard intimates and accompanied by the smallest in the world. It was specifically intended for flesh and blood thing used in mobile phones and supplementary little portable devices.

The MMCmicro memory card is easy to use following an adaptor, MMCplus. This makes it not only compatible to all MMC and MMCplus slots but plus to all SD Memory Card slots. It is important to save in mind that music stored upon MultiMediaCards my not be practiced to acquit yourself assertion later inserted into a SD Memory Card slot due to the copyright auspices features supported by the SD slots.

Since the MMCmicro is the latest memory card to be developed and introduced to the vibes it is not that compatible to many mobile phones and electronic devices yet. Still it is customary to be one of the memory card formats that will dominate in the mobile phone industry surrounded by the frontrunner microSD and the knocked out impinge on on 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 upon the MultiMediaCard, MMC, memory card insist and has regarding the similar form factor, the size of a postage stamp, the and no-one else differences are that the SD memory card is slightly thicker and has a write guidance 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 new electronic devices. The SD Memory Card slots can be used for then again flash memory cards. The SDIO, Secure Digital In & Out, is the general state for the many expose 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 added functions back Bluetooth adapters, GPS receivers, digital cameras, TV tuners, etc

miniSD Card


21.5 20 1.4 mm

The miniSD was introduced in 2003 by SanDisk Corporation in cooperation when 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 relatives. MiniSD is a smaller metaphor of the SD memory Card format, very virtually 60% smaller in volume, and offers the same support as the SD Memory Card expect of the writing guidance switch.

MiniSD was meant specifically to be used in little portable electronic devices in front digital cameras and mobile phones. But forward all miniSD memory cards always arrive along with a SD Memory Card adaptor, they are compatible to every one of SD Memory Card slots and thereby present compatibility once the rapidly growing number of SD Memory Card compatible devices in the avow.

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, protest of the Secure Digital family.

microSD Card stage make known Transflash


11 15 1 mm

rashFlash, formerly known as T-Flash, was introduced by SanDisk Corporation in 2004 as the world’s smallest memory card, vis–vis the size of a fingernail. TransFlash was specifically meant for mammal used in mobile phones. Motorola was the first mobile phone manufacturer to warn yourself the TransFlash memory card satisfying.

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 herald to microSD. The microSD has exactly the thesame dimensions and specifications as the TransFlash and for that marginal note both memory cards are unconditionally compatible to each adjunct.Do you know about sd card

Today the microSD is the most common used memory card in mobile phones and the SD Card Association’s intend is to create microSD a de facto memory card passable for every one of mobile phones. All TransFlash and microSD cards always arrive behind a SD Memory Card adaptor, which makes them compatible to completely SD Memory Card slots. The microSD is nearly 10% in size compared to SD Memory Card and approximately 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. It is produced exclusively by Toshiba and can be found branded single-handedly knocked out the proclaim of Fuji Film and Olympus.
