ABSTRACT:
A semiconductor memory device comprises a gate electrode provided via a gate insulating film on a semiconductor layer formed on a substrate and two diffused semiconductor regions provided to form a field effect transistor together with the gate electrode. An electrical charge is supplied to one of the diffused regions from the other region to thereby vary a width of a space charge layer appearing around the one diffused region so that informations "1" and "0" are selectively stored in the device. The stored information is read-out by detecting presence or absence of a buried channel between the space charge layer and the substrate.
