摘要:
The semiconductor memory device includes a plurality of memory cell arrays and a control circuit that outputs a first signal and a second signal. The first signal instructs start of precharging of each memory cell array. The second signal instructs completion of the precharging and transition to a read access. The first signal is wired through one or more delay circuits to arrive at each memory cell array with a time difference, and the second signal is wired not through the one or more delay circuits.
