Semiconductor recording apparatus and semiconductor recording system

A semiconductor recording system comprising:

• a host device;
• and
• a semiconductor recording apparatus connected to said host device,
• wherein said semiconductor recording apparatus includes:
• a semiconductor memory composed of a plurality of physical blocks;
• and
• 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,
• and wherein said semiconductor recording apparatus records data written by said host device and reads recorded data,
• and wherein the host device issues a logical-to-physical conversion table initialization command to said semiconductor recording apparatus in performing logical-formatting of the semiconductor recording apparatus,
• and wherein said semiconductor recording apparatus further includes a logical-to-physical conversion table initializing section for updating a plurality of physical addresses corresponding to a plurality of logical addresses of said logical-to-physical conversion table into invalid addresses based on the performance of the logical-formatting in which the logical-to-physical conversion table initialization command is issued from the host device.
