Abstract:
The present invention relates generally to an integrated circuit (IC) design, and more particularly to a method and apparatus for providing an SRAM cell with improved read and write margins. The method includes providing a first negative voltage to a bit-line and a supply voltage to an inverse bit-line to increase a first potential difference between the bit-line and the inverse bit-line during a write operation of a logic “0.” The method also includes providing the first negative voltage to the inverse bit-line and the supply voltage to the bit-line to increase the first potential difference during a write operation of a data “1.”
