Information handling system with SRAM precharge power conservation
Abstract:
An information handling system (IHS) includes a processor with on-chip or off-chip SRAM array. After a read operation, a control circuit may instruct the SRAM array to conduct a precharge operation, or alternatively, instruct the SRAM array to conduct an equalize bitline voltage operation. A read operation may follow the precharge operation or the equalize bitline voltage operation. The control circuit may instruct the SRAM array to conduct an equalize bitline voltage operation if an equalized voltage of a bitline pair exhibits more that a predetermined amount of voltage. Otherwise, the control circuit instructs the SRAM array to conduct a precharge operation before the next read operation.
