Abstract
A semiconductor device includes a semiconductor substrate and a first memory cell disposed on the semiconductor substrate. The first memory cell includes a first write and erasure transistor, a first read transistor, and a first charge transfer reduction transistor. The first write and erasure transistor controls data writing and erasing. The first read transistor controls data reading. The first charge transfer reduction transistor reduces injection of an electric charge to the first write and erasure transistor and the first read transistor.
