Abstract
A semiconductor memory device includes a cell array including a plurality of memory cells connected between a first bit line and a source line; a computation control circuit configured to control a first bit line current between the first bit line and the source line during a computation operation; and an output circuit including a first computation capacitor whose charge amount is changed according to the first bit line current during the computation operation, wherein an amount of charge that flows between the first bit line and the source line during the computation operation depends on both data stored in a memory cell among the plurality of memory cells according to a first data and a voltage of a word line connected to the memory cell provided according to a second data.
