ABSTRACT:
A semiconductor memory device comprises a plurality of memory cells connected to a bit line, and a sense amplifier of the current sense type. The sense amplifier includes an initial charging circuit capable of initially charging the bit line with a suppressed value of current only for a certain starting period during an initial charging period. The sense amplifier detects a value of current flowing in the bit line to decide data read out of each of the memory cells.
