VALIDATION OF DRAM CONTENT USING INTERNAL DATA SIGNATURE

Abstract:

Systems, methods, and apparatus related to validating data stored in a memory system. In one approach, a DRAM stores data for a host device. A controller that manages the DRAM receives a command from the host device to generate a signature. The controller also receives data from the host device that indicates a region of the DRAM. In response to receiving the command, the controller reads data from the indicated region. A signature is generated by the controller based on the data read from the indicated region. The generated signature is sent to the host device in response to the command.
