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.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
