STATIC RANDOM ACCESS MEMORY AND DRIVING METHOD THEREFOR

摘要

A static random access memory comprises: a pre-charge unit for supplying a pre-charge voltage to first and second bit lines connected to a bit cell; a capacitor of which one terminal or the other terminal is selectively connected to a ground terminal; a clamping unit for regulating the voltage level of a bit line by selectively connecting the bit line with the capacitor; and a MUX unit which is included in a unit memory cell comprising the bit cell, the pre-charge unit, the capacitor and the clamping unit, and which activates the bit line of the unit memory cell upon receiving a selection signal, wherein the clamping unit connects the first and second bit lines with the capacitor according to a charge sharing control signal to thereby induce charge sharing of the first and second bit lines and the capacitor.
