ABSTRACT:
A pair of load transistors of a flip-flop circuit constituting a memory cell consist of thin film transistors, and channel regions of the pair of load transistors overlap drain regions of the transistors through a gate insulating film. For this reason, a channel length of the load transistor can be sufficiently increased, and a leakage current of the load transistor can be reduced.
