针对目前固态硬盘主控国产化自主可控的需求,设计了一款采用PCI E接口的数据存储控制电路。该方案与SATA 2.0接口相比,采用了PCI E2.0×2的形式,其读写速度有了明显提高。在主控芯片中对固态硬盘的可靠性采取了众多策略,大大延长了NAND FLASH的使用寿命,安全性方面采用国密SM3、SM4和AES256进行加密,同时使用闪存阵列管理使得多通道可以并行进行,数据销毁上可以选择智能销毁和物理销毁两种方式,在紧急情况下最大限度的保证了用户信息的安全。

For the current solid-state hard drive master control of the domestic control of the demand, we design a PCIe interface data storage control circuit. The program compared with the SATA 2.0 interface, using the form of PCIE2.0 × 2, the read and write speed has been significantly improved. In the master chip on the solid-state hard drive reliability using a number of strategies, greatly extending the NAND FLASH life, using dense SM3,SM4 and AES256 encryption in security aspects, using flash memory array management technology allows multi-channel can run in parallel, data destruction can choose intelligent destruction and physical destruction in two ways, in the event of an emergency It） ensure maximum user infor...
