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 17):
The semiconductor device according to  claim 16 ,\n wherein the semiconductor device further comprises:\n a first voltage signal wiring operable to supply the first voltage; and \n a second voltage signal wiring operable to supply the second voltage, and \n wherein the first signal wiring, the second signal wiring, the first voltage signal wiring, and the second voltage signal wiring are arranged in a same metallic wiring layer.
