Abstract
Provided is a sense amplifier circuit for detecting data having been read from a memory cell. The sense amplifier circuit includes: a potential control unit for controlling the potential of a bit line connected to a memory cell; a current amplifier unit for amplifying a readout current flowing from the memory cell to the bit line so as to produce an amplified current; and a detection unit for detecting data having been read from the memory cell on the basis of the amplified current. The potential control unit controls the potential of the bit line in a data readout duration, and the data readout duration includes a current amplification duration, and the current amplifier unit amplifies the readout current in the current amplification duration.
