SEMICONDUCTOR MEMORY DEVICE

摘要

A semiconductor memory device includes a memory cell, a sense amplifier electrically connected to the memory cell, the sense amplifier including a node for sensing a voltage during a sense operation and a data latch electrically connected to the node and configured to hold a first voltage corresponding to a voltage of the node when a strobe signal is issued during a strobe operation, and a controller configured to raise the voltage of the node during the strobe operation before the strobe signal is issued.
