Toshiba and Qualcomm begin production standard UFS 2.0, internal memory twice as fast in 2014


left;”> many years, Android smartphones and tablets use flash eMMC storage. These internal reports are somewhat similar to NAND SSDs used in computer mode, so much so that many times is often confused with each other. SSDs are distinguished from traditional because they are much faster. In mobile eMMC memory is not the case, so it appears the standard UFS (Universal Flash Storage), which aims to become an improved internal eMMC memory successor.

left;”> MMC memory (MultiMediaCard) have been in use since 1997 and with each new version its speed has increased . Of 104MB / s (eMMC V4.41) to 200MB / s (V4.5) until 400MB / s in the last and current version V5.0 eMMC. However, to be based on a particular interface 8-bit, have a serious scaling problem and improve in the following versions is very complex. And this is where it appears UFS and serial interface .

Toshiba was who last year launched its first version and now plan their mass production 2.0 for UFS devices incorporated into the range high this year 2014.


Of these new reports have been developed two; HS and HS-G2-G3 , which offer speeds of 5.8Gbps (about 725MB / s ) and 11.6 Gbps (about 1.45 GB / s ) respectively. As we see, double the 400MB / s that provides eMMC V5.0.

Another advantage is achieved not only the speed, but we can read and write to the disk at a time (I sounds as R / W in root explorer?). In addition to putting queued commands.

These improvements which have come to achieve is that confirm the JEDEC standard for 2014 , and even now are even more expensive than eMMC their long-term improvements are clear. Increasingly mobile and demanding more content as the 4K read speeds demand high.

The first manufacturer hug has been Qualcomm technology , in talks with Toshiba has announced that incorporate compatibility with UFS 2.0 in its new Snapdragon 805, making those phones with the Qualcomm processor that could be the first UFS 2.0 out internal memories. The eMMC memory will continue to be present for a time in the input range, but smartphones or high-end tablets this 2014 will receive a clear jump in improving its internal storage.
