Non-volatile semiconductor memory device.

摘要

A non-volatile semiconductor memory device having a plurality of non-volatile memory cells, each cell having a floating gate (6) and control gate (8) above a channel region (1a) sandwiched between a source region (2) and drain region (3) on the surface of a semiconductor substrate (1), and the channel region (1a) on the drain region (3) side facing the floating gate (6) via a thick insulating film (4).
