Original Abstract Submitted
A memory system includes a semiconductor memory device and a memory controller configured to send a command to the device. The device includes a memory cell connected between a bit line and a source line, a sense amplifier having a first transistor provided between at least two transistors of the sense amplifier and the bit line, and a sequencer. The sequencer, in response to the command, reads data stored by the memory cell by applying a first voltage to the first transistor and a second voltage to the source line during a first time period, applying a third voltage to the first transistor and a fourth voltage to the source line during a second time period after the first time period, and applying the first voltage to the first transistor and a fifth voltage to the source line during a third time period after the second time period.
