Top of four types of MMC cards (clockwise from left): MMC, RS-MMC, MMCplus, MMCmobile, metal extender ... Reduced Size MultiMediaCard (RS‑MMC), introduced in 2002, is a smaller variant of MMC, measuring approximately 24 by 18 by 1.4 millimetres (0.945 in × 0.709 in × 0.055 in), about half the height of a standard MMC. It uses a simple extender to work in standard MMC or SD slots and was available in capacities up to 2 GB. Some manufacturers, including Nokia and Siemens, briefly adopted RS‑MMC in their early Symbian-based smartphones and tablets. In response to this fragmentation, SanDisk partnered with Siemens and Nokia in 1996 to create a universal, compact memory card standard. The resulting format, known as the MultiMediaCard (MMC), was officially introduced in 1997. Even Nokia, one of the original backers, was slow to integrate MMC into its popular handsets. In an effort to boost adoption, the MMCA introduced revised specifications between 2004 and 2007, including reduced power consumption, support for smaller form factors, and increased storage capacities. However, these updates had limited market impact. MMC technology served as the foundation for the development of the Secure Digital (SD) card standard. MultiMediaCard (MMC) is a memory card standard used for solid-state storage, originally introduced in 1997 by SanDisk, Siemens, and Nokia. Designed as a compact, low-pin-count, postage‑stamp‑sized card alternative to earlier storage solutions, MMC uses a serial interface and a single memory ... The MMCplus and MMCmobile formats were introduced in 2004 and the MMCmicro format in 2005 as part of version 4 of the MMC specification with several enhancements to improve performance and better compete with SD cards. These enhancements included support for higher clock speeds (26 MHz and 52 MHz alongside the normal 20 MHz) and wider data buses (8‑bit alongside the previous 1- and 4‑bit), which combined to enable a 52 Mbit/s transfer rate, alongside dual-voltage support (1.8 V and 3.3 V) carried over from DV‑MMC. The full‑size enhanced format was marketed as MMCplus, while its smaller counterpart, matching the size of RS-MMC, was known as MMCmobile.

Newer RS-MMC cards, used in Nokia's newer phones (like the Nokia 6630 and Nokia 6680), support a lower voltage (1.8 V instead of 3 V) mode to reduce battery demand, and these lower-voltage RS-MMC cards, known as Dual Voltage Reduced Size MMC, and can be marketed as MMCmobile when they meet the MMCmobile card standards. MMC cards also come in a smaller form factor, of about half the size: 24mm x 16mm x 1.5mm. This alternate form factor is known as Reduced-Size Multi-Media Card. These low-voltage cards are backwards compatible with older RS-MMC devices. The dual voltage cards, and the MMCmobile are part of the MMC 4.x standards. ...

why does nokia use mmc instead of sd? | Howard Forums - Your Mobile ...

An SD card slot can accept EITHER SD or MMC, but an MMC slot CANNOT support an SD card, if that makes sense. The reason is SDs have more contacts on the card, and are actually slightly (barely noticable) smaller, I believe. (or larger, I don't remember, but I know it's miniscule.) I personally would like to see Nokia go to Transflash instead of RS-DV-MMC and all that nonsense. In the meantime, with the use of adapters, compatible devices can handle MiniSD, RS-MMC, DV RS-MMC, MMCMobile and TransFlash. Those adapters often come with the purchase package of the memory cards. The most confusing about MMC is the variants: there will be another one, MMCmicro! ... The different types of flash memory can make your head spin. The marketplace is trying to pear down the types, but manufacturers, like Nokia, just will not let go of the older technology. So manufacturers will always look at getting the best card that will meet their needs for the particular device. Nokia has gone from mmc to rs-mmc to dv-rs-mmc and now minisd, for a number of reasons- physical size, power consumption, data transfer speeds, card availability etc. it seems like every other electronics device (pda, camera) has or is migrating towards sd. does nokia have vested interest in mmc standard?

What Is MMC Card and The Difference between MMC and SD Card

MMC cards paved the way for most of the hardware that we use today. Read this piece to learn what is an MMC card (MultiMedia Card) and how to recover data from it. The average MMC is about the size of a postage stamp: 24 mm x 32mm x 1.4 mm. It uses NOR-based flash technology to store data, which SanDisk pioneered. It means that the card can store information in the form of electrical signals rather than the magnetic methods used by conventional optical disks. The process of storing data allows for ample storage capacity for MMC cards despite their compact design. Today, you can get MMC cards capable of holding up to 512 gigabytes. Moreover, their lack of data surface exposure makes them much more durable than SD cards. Most smartphones use embedded MMC (eMMC) for internal storage. They used a surface contact low-pin interface that allowed easier access and data storage than hard drives. This technology became a crucial part of the development of solid-state drives. Earlier multimedia cards had a capacity of 32 MB, but variants with more than 1 GB storage were available by the late 2000s. The gaming industry welcomed the technology wholeheartedly, with numerous video game consoles using MMC cards as external storage.

It was around half the size of an MMC card, but with an adaptor could be used in an MMC slot. MMCmobile was a later variant of RS-MMC introduced in 2005, the main difference being that MMCmobile was dual-voltage, and could operate in later mobile phones with a low-voltage (1.8V) slot, as well as older phones using 3V. Nokia and Siemens were the only manufacturers to make use of RS-MMC/MMCmobile, and by 2006 had Nokia had switched to miniSD or microSD while Siemens exited the mobile phone business. The Reduced-Size MultiMediaCard (RS-MMC) was a smaller variant of MultiMediaCard, introduced in 2004 and used almost exclusively in mobile phones. It was around half the size of an MMC card… This website uses cookies to improve your experience while you navigate through the website.
