Rapid technological change: 3D NAND and PCIe NVMe SSD promoted the market mainstream

To the same cost, it can achieve double the capacity of various memory makers on the 3D NAND innovative technology strong input, predicted in 2017 will become the 3D NAND solid-state drive (SSD) outbreak of the starting point of the outbreak. Coupled with Intel's Non-Volatile Memory Express (NVMe; non-volatile memory high-speed specifications) ultra-high transmission interface popular debut. The new generation of SSD products, excellent price performance ratio is expected to be substantially narrowed the gap with the traditional hard drive market size, the two storage devices have gradually approached the gold cross point, High-speed large-capacity SSD will become a variety of system equipment and consumer preferences.

According to research firm Research and Markets, the survey released in late September noted that the PCIe SSD market will have a compound annual growth rate (CAGR) of 33.24 percent between 2016 and 2020. One of the key reasons for the significant growth in the market is Samsung, Micron, Intel and Toshiba and other manufacturers, the total investment in 3D NAND up to 18 billion US dollars in production R & D funding. Which Intel plans to 2015, the Chinese market invested 550 million US dollars to set up 3D NAND plant. Major manufacturers of 3D NADN technology continued to overweight, will be able to quickly expand the global SSD market during the forecast size.

Coupled with Intel's leadership in the development of NVMe interface standard, the system manufacturers to support and import, leaving PCIe SSD products show a new high-speed transmission style. NVMe can significantly improve read and write performance through high-bandwidth, low-latency PCIe bus transport channels, across SATA 6Gb / s and SAS 12Gb / s transmission bandwidth limits. NVMe PCIe SSD estimates will become the mainstream to replace SATA / SAS SSD, will also drive the SSD market demand.

In the face of the continuous innovation of 3D NAND technology and the evolutionary performance of NVMe interface standard, SSD manufacturers need more advanced control chip and firmware solution in order to develop and design SSD products with higher service life, speed, stability and reliability.

Silicon Motion Technology, the world's leading IC design company, today introduced two new generation of control chip solutions, the SM2258 and SM2260, designed specifically for 3D TLC NAND and NVMe PCIe SSD technology.

June SM2258, support mainstream 2D ​​/ 3D TLC NAND and SATA interface; published in August SM2260, it is in accordance with NVMe PCIe standard, support for 3D MLC / TLC SSD control chip. The comprehensive 3D NAND SSD market, combined with the most complete firmware solution, can be tailored for different NAND Flash, will help SSD manufacturers to develop the most competitive 3D NAND SSD products, leading the market to grab the first opportunity.

The SM2258 and SM2260 provide Huirong's turn-key complete solution with complete hardware and firmware technology for greater capacity, best-in-class performance, ultra-low power consumption, longer life and superior performance Of the data stability. In the show, SM2260 8-channel design, the maximum support 2TB capacity; with 3D NAND's NVMe PCIe high-speed transmission efficiency, read and write speed, respectively, can reach 2370MB / 1039MB alarming figures.

Both controllers use the NANDXtend ™ 3-D Erase Correction technology, which combines both LDCP and RAID Data Recover capabilities. Can greatly improve the P / E Cycle SSD more than 3 times, effectively extending the service life of SSD, and provide more efficient data correction and calibration capabilities, bringing the most stable data integrity.

Advanced error correction technology to significantly enhance the life and performance of SSD

New 3D stack and three-tier storage (TLC) design architecture, so NAND Flash chip capacity density surge, the cost down. However, SSD master correction error correction technology is even more important, especially in the more complex 3D NAND architecture, the need for efficient error correction correction technology, can ensure the stability of SSD, and also can upgrade SSD life and performance.
