Abstract
A system and method for efficient power, performance and stability tradeoffs of memory accesses are described. A memory includes an array of cells for storing data and a sense amplifier for controlling access to the array. The cells receive word line inputs for data access driven by a first voltage supply. The sense amplifier includes first precharge logic, which receives a first precharge input driven by the first power supply used by the array. Therefore, the first precharge input has similar timing characteristics as the word line input used in the array. The sense amplifier includes second precharge logic, which receives a second precharge input driven by a second power supply not used by the array and provides precharged values on bit lines driven by the second power supply.
