Abstract

Systems and methods for a bit-cell are presented. The bit-cell comprises a read-port circuit and a write-port circuit. The read-port circuit comprises four transistors, wherein the read-port circuit is activated by a first threshold voltage. The write-port circuit comprises eight transistors, wherein the write-port circuit is activated by a second threshold voltage. The write-port circuit is coupled to the read-port circuit. The first threshold voltage and the second threshold voltage may be different and may be provided by a single supply voltage.
