A semiconductor memory device includes a bit line pairs, a source line, a word line, and a memory cell array including a plurality of memory cells arranged in a row and column directions, wherein the memory cell is a pair of p-type transistors formed on an n-type well, wherein one of terminals of the transistor is a Schottky barrier junction consisting of a metal thin film formed on the n-type well, and the other terminal is connected to the source line.

Semiconductor memory device

A nonvolatile memory device includes one or more reference cell transistors, one or more memory cell transistors, and a current source circuit including three or more field effect transistors that have gates thereof connected together, the three or more field effect transistors including two or more field effect transistors and another field effect transistor, currents flowing through the two or more field effect transistors being combined to flow through the one or more reference cell transistors, and another field effect transistor having a drain thereof connected to one of the one or more memory cell transistors.
