2014- year from its very beginning was marked by a massive entry into the market of flash memory-based crystals MLC NAND, Micron produced using 20nm process technology. Earlier in the budget segment, dominated the 19-nm memory Toshiba and 25nm Intel / Micron memory, now in the form of replacement come Micron products, having a lower price .
But the 20-nm process technology is losing relevance: currently Micron unveiled 16 nm process technology memory, and even produced its own series of SSDs MX100 , based on it. And it means that we will have a new range of market restructuring .
Silicon Motion has prepared a new revision of its controller SM2246EN, which has been optimized specifically for the aforementioned 16-nm memory Micron.
Controller SM2246EN just focused on OEM-production: Silicon Motion not only develops controllers themselves, it also designs PCB , and creates the firmware. All this is freely available to customers for use in retail products.
Update revision has changed several performance characteristics. :
|
Old revisions |
The new revision |

80,000 IOPS |
67,000 IOPS |
Recording random blocks (4KB, QD = 32) |
75,000 IOPS |
65,000 IOPS |
As I noted above, the primary focus was on reducing the Micron cost , and not on the performance level .
Silicon Motion promised not only limited to one press release: The ongoing now in Taipei at Computex 2014 the company will demonstrate full working samples on the new SSD with Micron flash memory . Related Products :
