Abstract
According to an embodiment, a semiconductor memory device includes a first memory cell, a first interconnect, a first sense amplifier, a second interconnect, and a first latch circuit. The first interconnect is coupled to the first memory cell and extends in a first direction in a first interconnect layer. The first sense amplifier is coupled to the first interconnect. The second interconnect is coupled to the first sense amplifier and extends in the first direction in the first interconnect layer. The first latch circuit is coupled to the second interconnect. An end surface of the first interconnect on a side facing the first direction is opposed to an end surface of the second interconnect on a side facing a direction opposite to the first direction.
