This afternoon, Guoke Micro signed a contract with Loongson China Science and Technology and released the first national solid-state hard drive (SSD hard drive) control chip.

According to the agreement, Loongson Zhongke will use Guoke Micro as the preferred domestic SSD supplier in the follow-up motherboard program, and Guoke Micro will use Loongson Zhongke as the preferred supplier of embedded CPU IP core in the subsequent chip products. As the first strategic cooperation achievement, Guoke Micro released a new GK2302 series chip, equipped with Godson embedded CPU IP core, becoming the first solid-state hard disk control chip in China that truly realizes national production.

The core part of the SSD hard drive is the NAND flash and the main control chip. The main control chip is a very important part of the storage market, affecting the performance, stability and reliability of the SSD hard disk. If we compare the SSD hard drive to a large truck, the main control chip is equivalent to the cab. The firmware in the main control is equivalent to the driver, which determines how the truck is opened. At present, this market is mainly monopolized by foreign companies, such as Marvell and Toshiba.

The GK2302 series uses a high-speed SATA 6Gbps interface to communicate with the host. The single-chip capacity supports up to 4TB and the read/write speed reaches 500MB/s. Compared with the previous generation, the GK2302CPU has improved performance by 15%, power consumption by 6.5%, and full hard disk performance by 18.4%, reaching the international advanced level.

In addition, the GK2302 series redefines the four standards of localization: first, it is equipped with domestic embedded CPU IP core; second, it is completed in China from chip design to tape-off to production and packaging. The whole machine brand is fully adapted. Fourth, the integrated national secret encryption and decryption algorithm is safe and credible.

Undoubtedly, GK2302 will become a landmark achievement in promoting the construction of national network information security, opening a new milestone in storage nationalization.
