Abstract: Disclosed are a solid state drive and a write operation method. The solid state drive comprises: a controller, receiving write data from outside and comprising a first cache unit for storing the write data; a Flash memory, receiving the write data sent by the first cache unit according to a first instruction of the controller; a second cache unit, storing the write data from the first cache unit as backup data, and sending the backup data to the Flash memory according to a second instruction of the controller. The second instruction is obtained after the write data fails to be written into the Flash memory under the first instruction, so that the backup data can continue to be called if write operation fails. By combining advantages of the first and second cache units, efficiency and quality of write operations are improved and bandwidth requirements are lowered.

Abstract: The present disclosure relates to an implementation for a trusted computing system. According to the embodiments of the present disclosure, a master controller in an SSD, which is necessarily configured in the system, is used to provide all necessary security functionality of the system's RoT. The system does not need to contain any special RoT chip or module, does not need any modifications in the system design, is easy to adopt, and can be implemented by any system comprising a hard drive. All necessary security functions are completed by the master controller of the system's hard drive. Thus, not only can the cost of the security module be reduced, but more importantly, the mechanism directly protects information and resources (e.g., operating system, user programs, user data, etc.) that actually need to be protected in the system, and once the mechanism is enabled, the protection function cannot be bypassed.
