Patent 8004907 was granted and assigned to Freescale Semiconductor on August, 2011 by the United States Patent and Trademark Office.
A memory includes an SRAM bitcell including a pair of cross-coupled inverters, wherein a first inverter of the pair includes a first device having a body and a second inverter of the pair includes a second device having a body. A first selection circuit has a first input coupled to a first supply voltage terminal, a second input coupled to a second supply voltage terminal, and an output coupled to a first current electrode of the first device and to a first current electrode of the second device. A second selection circuit has a first input coupled to the first supply voltage terminal, a second input coupled to the second supply voltage terminal, and an output coupled to the body of each of the first and second devices. A word line coupled to the SRAM bitcell is driven by a word line driver coupled to the first supply voltage terminal.
