STORAGE DEVICE, INFORMATION PROCESSING SYSTEM, AND METHOD FOR CONTROLLING STORAGE DEVICE

摘要

The purpose of the present invention is to store control codes for controlling a non-volatile memory in the non-volatile memory and to improve the storage reliability thereof. A control code memory stores the control codes for controlling the non-volatile memory. A reading control unit reads the control codes from the control code memory prior to the operation of the non-volatile memory. An error correction unit corrects an error in the read control codes. A working memory holds the error-corrected control codes. A control unit controls the non-volatile memory on the basis of the control codes held in the working memory and outputs a command to request that the control code memory be rewritten with the control codes held in the working memory. A refresh control unit carries out the rewriting on the basis of the control code rewriting request command.
