Title: Negative resistance device

Abstract: A negative resistance device (NRD) has a MOSFET-like structure, and is biased by shorting the gate and source together at a fixed applied potential and applying a different fixed potential to the drain, and sweeping the bulk potential towards the drain potential, causing the bulk current to exhibit a negative resistance characteristic. The NRD may be used in a memory circuit (10) in which a resistor (R) is connected between the bulk (2) and a fixed potential. Two States of the circuit at which the current through the resistor matches that through the bulk of the NRD are stable, providing for bistable memory operation.
