Abstract
A semiconductor storage device having a plurality of block-erase type non volatile memory chips classifies the memory chips into memory groups of a number equal to twice the number of buffer memories provided in the storage device and assigns logic sector addresses sequentially to sectors contained in one erase block of each memory group in such a manner that the logic sector addresses are sequenced in series to those in the corresponding erase block of the next succeeding memory group.
