Abstract

In a non-volatile semiconductor memory of this invention, a memory cell array constituted by a plurality of memory cells is divided into a plurlaity of blocks, and erase lines which are common to the respective blocks and independent from each other are arranged. In the data write mode, a predetermined voltage is applied to only the erase line connected to a selected one of the blocks.
