Abstract
A memory cell includes a non-volatile p-channel transistor having a source coupled to a first potential, a drain, and a gate. A non-volatile n-channel transistor has a source coupled to a second potential, a drain, and a gate. A switch transistor has a gate coupled to a switch node, a source, and a drain. A stress transistor has a source and drain coupled between the drain of the non-volatile p-channel transistor and the drain of the non-volatile n-channel transistor, the stress transistor having a gate coupled to a gate bias circuit. Where one of the first or second potentials is a bit line, an isolation transistor is coupled between the other of the second potentials and one of the non-volatile transistors.
