Abstract
A semiconductor recording apparatus includes a logical-to-physical conversion tableshowing correspondence between a physical address of said semiconductor memory and a logical address and writes the table to a flash memory. On receiving a write command issued from a host device, a block management sectionselects a physical block with reference to said logical-to-physical conversion table, and updates said logical-to-physical conversion table. A logical-to-physical conversion table initializing sectionupdates a physical address corresponding to each logical address of the logical-to-physical conversion table into an invalid address. Accordingly the apparatus can render the number of rewrites of physical blocks uniform irrespective of writing conditions.
