Abstract
An electrically erasable and programmable memory device includes a memory cell array including a plurality of blocks, each including electrically erasable and programmable memory cells. A data input/output unit transfers data between the memory cell array and an external device. An address conversion unit converts an external address signal into a decoded signal applied to the memory cell array so that the correspondence between the external address and the plurality of blocks is changed so as to equally access the plurality of blocks for programming. The number of the plurality of blocks is greater than the number of blocks accessible by the external address signal.
