Abstract

A storage cell includes a first bit line, a storage circuit, and a pass transistor. The storage circuit has a first storage node for holding a logic state indicative of a logic value. The pass transistor is coupled to the first bit line and the first storage node for establishing a conduction path therebetween. The pass transistor receives a bias voltage to switch the pass transistor into a substantially nonconducting state when the storage cell is not being accessed. The reverse bias on the first transistor substantially reduces the leakage current through the pass transistor.
