Abstract

A memory circuit includes a plurality of bit lines. A first memory cell and a second memory cell are coupled in series. Each of the first memory cell and the second memory cell is capable of storing a first type datum. The first memory cell and the second memory cell share a first common source/drain (S/D) region. The first common S/D region is electrically isolated from all of the bit lines.
