Semiconductor disk drive and method of creating an address conversion table based on address information about defective sectors stored in at least one sector indicated by a management code

摘要

A semiconductor disk drive using a non-volatile memory of MGM such as flash memory, allowing swift access of nondefective sectors or blocks, and shortening the time for creating a logical/physical conversion table, and a method of creating the logical/physical address conversion table for the semiconductor disk drive. According to the disk drive and the method, the addresses of all defective sectors are stored in predetermined sectors or in a predetermined block during manufacturing process, and a CPU for internal control creates a logical/physical address conversion table in a memory for CPU, based on the sector addresses of all defective sectors.
