Abstract
In some embodiments, a system includes a bit-cell circuit and a body voltage control circuit. During a sleep mode, the bit-cell circuit receives, via a source node of a transistor, a retention voltage. During an active mode, the bit-cell receives, via the source node, an operating voltage. The body voltage control circuit includes a first transistor that connects a body node of the transistor of the bit-cell circuit to the source node such that during the sleep mode, the body node receives the retention voltage. The body voltage control circuit further includes a second transistor that connects the body node to a voltage source such that during the active mode, the body node receives the operating voltage.
