Abstract
A circuit includes a degeneration p-channel metal-oxide-semiconductor (PMOS) transistor, a load PMOS transistor, and a clamp transistor configured to clamp a voltage applied to a resistance based memory element during a sensing operation. A gate of the load PMOS transistor is controlled by an output of an operational amplifier.
