Samsung's 256Gb Memory Chip

Samsung going to launch 256Gb ultra-fast memory chips for smartphones
Whenever we are talking about the performance of smartphones we discuss its CPU (Central Processing Unit) and graphics. Just like these factors NAND flash performance is also very important, however it is an area where smartphone manufacturers often offer very different experiences. Samsung is going to launch a new storage standard for smartphone users called UFS (Universal Flash Storage). Now they are increasing its maximum memory density as well with a storage of 256Gb UFS-Capable NAND chips.

Universal Flash Storage

UFS (Universal Flash Storage) is basically substitute of embedded MultiMediaCard standard. SATA is slower than eMMC, eMMC transer rate is 400MB/s. eMMC has certian limitations, however it does not support out-of-order execution, the protocol is CPU intensive, queue depth is also limited and protocial is half duplex means it can only read or right at a time, but can not do both things simultaneously. To be fair, SATA itself suffers from this last limitation — but UFS doesn’t.


UFS supports the configuration of multiple bands - original specification at 580 MB / s bandwidth for transmission targeted, and the manufacturers to carry two lanes that meet a maximum of 1.2 GB / s. This significant jump in capacity over the EMMC and should allow for faster devices. In contrast to MCWE, which uses eight parallel rails communication UFS used serial connection with a high speed. EMMC used the parallel connecting channels UFS uses high-speed series.

Samsung said the new chips capable of 256GB 850MB sequential read / s and 260 MB / s sequential write. Speed ??reading is faster than a standard SSD can operate, but the write speed is slower than what we have been claimed by many modern SSDs. Samsung claims that the new chip and an interface capable of pushing 4K Ultra HD movies on the TV while additional files or clips are looking for - do not sweat desk, but a significant leap forward for the mobile device.

As for when we will see these opportunities into commercial products, the guess is as good as mine. smartphone manufacturers have not shown great interest in pushing the envelope to store - Apple continues to rely on its entry-level 16GB while Samsung starts with 32 GB. Zenfone 2 storage options Asus offers 256 GB, but not so many devices out there with this many features. I suspect part of the problem is that most users prefer to buy a low-end device, and then add the MicroSD card if you need more space, do not pay extra. smartphone manufacturers often sell storage in $ 100 steps - $ 100 to spend 32GB and 64GB, and $ 100 to go from 64GB to 128GB.

The good news is, adding a faster storage for smartphones should increase productivity, as it did for personal computers. Although it is based on NAND Flash, many smartphones offer a data rate of anemia - increased UFS brings should be a significant and welcome improvement.
