Estimating the term…
Data transferred from a host computer to a memory device is written into sectors whose addresses in a memory area are decoded by a decode tab. Old data to be updated by the above data is erased or marked with erase flags. At a predetermined point of time, in order to create free areas, necessary data is evacuated to a primary memory media and unnecessary data indicated by erase flags is erased by a unit of predetermined memory size. Part of the memory media which has become defective is marked with a defect flag, and is replaced by an alternate area. In doing so, the decode table is rewritten to rearrange the memory area.
A management method of writing data in a memory device with a memory area unable to be overwritten on a bit-specific basis, the memory area having a plurality of sectors and said memory device erasing and writing data by a unit of one sector, said method comprising:
