Abstract
A flash disk card using a flash memory is provided with MPU for converting the cylinder, head and sector numbers, which are input from a host device, into a logical block address (LBA) and a sector address in block format, determining a physical block address (PBA) having the same size as that of an erase block from the logical block address with reference to a logical/physical block address conversion table stored in the flash memory, and accessing the flash memory on the basis of the physical block address. The flash disk card permits a decrease in size of the address conversion table, can be constructed at low cost, and has no need for constructing the table at each time a power supply is turned on.
