Abstract:
This disclosure concerns a semiconductor memory device including bit lines; word lines; semiconductor layers arranged to correspond to crosspoints of the bit lines and the word lines; bit line contacts connecting between a first surface region and the bit lines, the first surface region being a part of a surface region of the semiconductor layers directed to the word lines and the bit lines; and a word-line insulating film formed on a second surface region adjacent to the first surface region, the second surface region being a part of out of the surface region, the word-line insulating film electrically insulating the semiconductor layer and the word line, wherein the semiconductor layer, the word line and the word-line insulating film form a capacitor, and when a potential difference is given between the word line and the bit line, the word-line insulating film is broken in order to store data.
