Abstract
A multi-supply dual port register file is disclosed. The register file may be used for transferring data between two power domains that operate on different voltages or frequencies. The register file comprises a memory cell that stores the data transferred between the domains. The memory cell may be independently supplied by a reference voltage independent of that of the memory periphery. A write power domain write data to the memory cell in accordance with its operating voltage and frequency and an independent read power domain may read data from the memory cell in accordance with its independent operating voltage and frequency. The register file facilitates efficient crossing between the read and write power domains.
