A memory circuit system and method for using the same are provided. In one example, the memory circuit system includes a memory array, a first precharge circuit, and a second precharge circuit. The memory array writes a first set of columns of the memory array. The first precharge circuit charges bitlines of a second set of columns of the memory array while bitlines of the first set of columns discharge. The first set of columns is different from the second set of columns. The second precharge circuit charges the bitlines of the first set of columns after the memory array has finished writing the first set of columns.

Pseudo-2-port memory with dual pre-charge circuits

A dual-rail memory includes, in part, a memory array that operates using a first supply voltage, and a periphery circuit that operates using a second supply voltage. The periphery circuit includes, in part, a clock generation circuit and a comparator. The dual-rail memory also includes a level shifter that varies the voltage level of a number of signals of the memory between the first and second supply voltages. The clock generation circuit is adapted, among other operations, to generate a read clock signal in response to a read request signal. The level shifter is adapted to supply a reference wordline read signal in response to the read clock signal. The comparator is adapted to select a delay between the read clock signal and the reference wordline read signal in response to a difference between the first and second supply voltages.
