Abstract
A semiconductor memory includes a first and a second transistor each with one of source/drain connected to a first wiring. The other of the source/drain for each of first and second transistor is connected to the gate of the other transistor. A third and a fourth transistor each have gates connected to a second wiring, one of source/drain of each connected to a third or fifth wiring, the other of the source/drain connected to the other of the source/drain of the first or second transistor. For the third transistor, a gate insulation layer includes a first ferroelectric material. For the fourth transistor, and a gate insulation layer includes a second ferroelectric material.
