Abstract:
Cell power supply lines are arranged for memory cell columns, and adjust impedances or voltage levels of the cell power supply lines according to the voltage levels of bit lines in the corresponding columns, respectively. In the data write operation, the cell power supply line is forced into a floating state according to the bit line potential on a selected column and has the voltage level changed, and a latching capability of a selected memory cell is reduced to write data fast. Even with a low power supply voltage, a static semiconductor memory device that can stably perform write and read of data is implemented.

Claim (Index 23):
A semiconductor device comprising:\n a pair of bit lines including a first bit line and a second bit line; a plurality of word lines; a pair of power lines including a first power line and a second power line a plurality of memory cells coupled to the pair of bit lines, the plurality of word lines and a pair of power lines so that one memory cell is coupled to one of the plurality of word lines, the pair of bit lines and the pair of power lines; and an assist circuit coupled to the pair of bit lines and the pair of power lines, wherein the assist circuit comprises; a first inverter including an input node coupled to the first bit line and an output node coupled a first MOS transistor; a second inverter including an input node coupled to the second bit line and an output node coupled a second MOS transistor; the first MOS transistor including a gate coupled the output node of the first inverter and a source-drain path coupled between a first voltage node for supplying a first voltage and the first power line; and the second MOS transistor including a gate coupled the output of the second inverter and a source-drain path coupled between the first voltage node and the second power line.
