ABSTRACT:
A semiconductor memory device includes: a device substrate having a semiconductor layer separated by a dielectric layer from a base substrate; a memory cell array having a plurality of memory cells formed and arranged on the semiconductor layer of the device substrate, each the memory cell having a MOS transistor structure with a body in an electrically floating state to store data based on a majority carrier accumulation state of the body; and a sense amplifier circuit configured to read out data of a selected memory cell in the memory cell array to store the read data in a data latch, then transfer the read data to an output circuit and write back the read data into the selected memory cell.
