Patent ID: 7710815

Claim:
An access unit for a static random access memory (SRAM), comprising: a first inverter, comprising a first power terminal, a first input terminal and a first output terminal; a second inverter, comprising a second power terminal, a second input terminal and a second output terminal; a first power switching element; and a second power switching element; wherein the first input terminal is electrically connected with the second output terminal, the second input terminal is electrically connected with the first output terminal, the first power terminal is electrically connected with the first power switching element and receives a first variable voltage through the first power switching element, the second power terminal is electrically connected with the second power switching element and receives a second variable voltage through the second power switching element, and when a status of the SRAM flips transforms and the first variable voltage is smaller than a reference value, an output charging current of the first inverter is decreased so that a discharging current at the first output terminal when transforming is increased.
