Abstract:
A semiconductor storage device provided can increase a write margin and suppress increase of a chip area. The semiconductor storage device includes plural memory cells arranged in a matrix; plural bit-line pairs arranged corresponding to each column of the memory cells; a write driver circuit which transmits data to a bit-line pair of a selected column according to write data; and a write assist circuit which drives a bit line on a low potential side of the bit-line pair of a selected column to a negative voltage level. The write assist circuit includes first signal wiring; a first driver circuit which drives the first signal wiring according to a control signal; and second signal wiring which is coupled to the bit line on the low-potential side and generates a negative voltage by the driving of the first driver circuit, based on inter-wire coupling capacitance with the first signal wiring.

Claim (Index 9):
A semiconductor device comprising:\n a word line; a pair of bit lines; a static type memory cell coupled to the word line and the pair of bit lines; a write driver circuit which transmits data to the pair of bit lines according to write data; and a write assist circuit which drives one of the pair of bit lines to a level of a negative voltage, the one of the pair of bit lines corresponding to a low potential side of the pair of bit lines according to the write data, wherein the write assist circuit comprises:\n a first signal wiring; and \n a second signal wiring coupled to the bit line on the low potential side and operable to generate the negative voltage based on a first coupling capacitance between the first signal wiring and the second signal wiring, and \n wherein the bit line on the low potential side is a wiring different from the second signal wiring.
