Abstract:
A static random access memory (SRAM) cell includes a storage unit configured to store a data bit in a storage node. The SRAM cell further includes an access unit coupled to the storage unit. The access unit is configured to transfer current to the storage node when a word line is asserted. The SRAM cell further includes a row header configured to provide current from a power supply when the word line is not asserted, and to not provide current from the power supply when the word line is asserted. The SRAM cell further includes a column header configured to provide current from a power supply when a write column line is not asserted, and to not provide current from the power supply when the write column line is asserted.
