Abstract: A memory device biasing circuit is disclosed, the circuit having a pair of semiconductor devices coupled to receive a supply voltage having a supply voltage level suitable for operating a memory device in an active mode and operable for providing an adjustable biased voltage to the memory device that is greater than a minimal voltage level for operating the memory device in a data retention mode. The pair of semiconductor devices includes a first semiconductor device; and, a second semiconductor device that includes an opposite type of semiconductor device than the first semiconductor device such that the pair of semiconductor devices includes each of an N-type semiconductor device and a P-type semiconductor device. The memory device biasing circuit further includes a bias adjustment circuit coupled to the second semiconductor device and configured to adjust the operation of the second semiconductor device based on the supply voltage.
