Abstract
A semiconductor memory device includes: a memory cell array including a plurality of memory cells each connected to a bit line pair; and a write circuit that brings a low potential-side bit line to a negative potential in response to a negative potential boost signal. At the data read operation, a word line is activated after a lapse of a first predetermined time from a transition of an input clock signal, to read the memory value of the memory cell. At the data write operation, the word line is activated after a lapse of a second predetermined time longer than the first predetermined time from a transition of the input clock signal, and the negative potential boost signal is activated after a lapse of a third predetermined time longer than the first predetermined time.
