Abstract
A semiconductor storage device includes a memory cell array having a plurality of memory cells connected to bit line pairs. At the time of data read from a memory cell, a replica bit line signal is output to a replica bit line in response to a replica word line signal, and a sense amplifier startup signal changes in response to the replica bit line signal whereby a sense amplifier is driven. At the time of data write into a memory cell, a low potential-side bit line of a write-target bit line pair is brought to a negative potential in response to a negative potential boost signal output from a negative potential generation circuit.
