Patent ID: 8751770

Claim:
A semiconductor recording apparatus including a semiconductor memory composed of a plurality of physical blocks, for recording data written by a host device on said semiconductor memory and reading recorded data, comprising: a block management section which records a logical-to-physical conversion table showing correspondence between a plurality of physical addresses of said semiconductor memory and a plurality of logical addresses on said semiconductor memory, selects a physical block corresponding to a logical block in a command issued from said host device with reference to said logical-to-physical conversion table, and updates said logical-to-physical conversion table upon data writing for implementation of address management; a logical formatting detecting section for detecting accomplishment of logical formatting for the semiconductor memory; and a logical-to-physical conversion table initializing section for updating a plurality of physical addresses corresponding to a plurality of logical addresses of the logical-to-physical conversion table, respectively, into invalid addresses based on a detection of logical formatting by said logical formatting detecting section.
