Abstract:
A semiconductor memory device includes a first memory cell transistor, a first bit line electrically coupled to the first memory cell transistor, a first sense amplifier, and a first latch circuit. The first sense amplifier includes a first node coupled to the first bit line, a first transistor including one end electrically coupled to the first latch circuit, a second node coupled to a gate of the first transistor, and a second transistor coupled between the first and second nodes. The second transistor is in an ON state during an operation of transferring a charge from the first bit line to the first and second nodes in accordance with data of the first memory cell transistor. The second transistor is in an OFF state during an operation of transferring data of the second node to the first latch circuit.
