Abstract
According to an embodiment, a semiconductor device includes M write word lines, M read word lines, N write bit lines, N read bit lines, N source lines, and M×N cells. The M×N cells are arranged in a matrix including M rows×N columns. A cell in an m-th row×an n-th column includes a first FET, a second FET, and a capacitor. The first FET is connected to an m-th write word line at a gate, to an n-th write bit line at a drain, and to a source of the second FET at a source. The second FET is connected to an m-th read word line at a gate and to an n-th read bit line at a drain. The capacitor is connected to an n-th source line at one end and to the source of the first RET at the other end.
