ABSTRACT:
A semiconductor memory device includes a plurality of memory cells organized in a matrix structure and a sense-amplifier circuit for detecting a voltage at a digit line which changes in accordance with the stored information in the accessed memory cell. The sense-amplifier circuit includes at least six field effect transistors of which two pair each are for effecting current amplification to produce a sense output to an inverter circuit or through a comparison detector or directly. The amplification of current is increased and the amplitude of sense-amplifier output voltage is reduced so that the sense-amplifier output can be inverted at a high speed.
