Abstract
A semiconductor memory device includes a replica circuit including a plurality of replica cells (RMC) having the same elements as those of memory cells in a memory array and outputting signals with levels in the stage number to a common replica bit line, and a sense amplifier control circuit for receiving a signal of the replica bit line to control a timing of a signal SAE for starting a sense amplifier circuit. The replica circuit includes a switching circuit (SW) for switching the stage number of the replica cells to be activated among the plurality of replica cells in a programmable manner.
