With the development of semiconductor technology, the capacity density of non-volatile storage (NVM) media represented by NAND flash memory continues to increase, and the capacity cost continues to decrease. At the same time, it also has advantages such as fast random access response and high aggregate throughput. SSD based on NAND flash memory has become an ideal option to store active data in the system instead of replace mechanical disks.
TAI is an NVMe SSD controller designed by DERA for enterprise and data center, based on data reliability assurance and flash memory performance aggregation core technology. TAI controller supports up to 16 NAND channels and mainstream device models from multiple NAND manufacturers, at the same time provides flexible configuration options. Based on TAl controller, developers can build enterprise NVMe SSDs with leading reliability and performance.
