Patent ID: 8610197

Claim:
A nonvolatile memory that retains data in a nonvolatile manner, formed of a transistor, comprising: a first gate electrode formed over at least one portion of one surface of a semiconductor layer that becomes a channel region formed between a source region and a drain region of said transistor through a first insulating film; a charge storage layer formed over at least one portion of the other surface of said semiconductor layer on an opposite side from the one surface having said first insulating film through a second insulating film; and a control gate connected to said charge storage layer, wherein at least one end of said first gate electrode overlaps said source region through said first insulating film, wherein one end of said charge storage layer overlaps said drain region through said second insulating film, and the other end is separated from said source region and overlaps said semiconductor layer through said second insulating film, wherein: between said source region and said drain region, in a first region that is adjacent to said source region, one end of said first gate electrode overlaps said source region through said first insulating film, and the first region includes said first gate electrode; and in a second region that is adjacent to said first region on an opposite side from said source region, at least one end of said charge storage layer overlaps said drain region through said second insulating film, and the second region includes said charge storage layer and said first gate electrode.
