Abstract

Using charges accumulated in a capacitance element connected to a drain side node of a memory cell, data is written in accordance with source side injection method. The capacitance value of the capacitance element is changed in accordance with the value of write data. A non-volatile semiconductor memory device allowing writing of multi-valued data at high speed with high precision is achieved.
