  • Voltage compensated tracking circuit in SRAM
    Patent number: 8284626
    Abstract: Supply voltage compensated tracking circuit in a split-rail static random access memory (SRAM). The circuit includes a tracking circuit for tracking a delay required for generating sense amplifier enable (SE) signal in a memory. The tracking circuit receives an array supply voltage (VDDAR) and a periphery supply voltage (VDDPR). Further, the circuit includes a discharge control circuit, operatively coupled to the tracking circuit, for increasing delay in activating a first transistor of the tracking circuit when VDDAR is higher than VDDPR; and a contention circuit including an output coupled to the first transistor, for delaying a discharge path activation through the first transistor when VDDAR is lower than the VDDPR.
