Patent ID: 8742502

Claim:
An accumulated charge control (ACC) floating body metal-oxide-semiconductor field effect transistor (MOSFET) comprising: a gate; a drain; a source; a body, wherein the body comprises a gate modulated conductive channel between the source and the drain; a gate oxide layer positioned between the gate and the body; and an accumulated charge sink (ACS) operatively coupled to the body, wherein the ACS comprises material selected to shift a capacitance versus voltage inflection inside the ACS outside of an operational body bias voltage range; wherein accumulated charge is present in the body of the floating body MOSFET when the MOSFET is biased to operate in an accumulated charge regime, and wherein the gate modulated conductive channel, source, and drain have carriers of identical polarity when the MOSFET is biased to operate in an on-state and wherein the MOSFET operates in the accumulated charge regime when the MOSFET is biased to operate in a off-state and when the accumulated charge has a polarity that is opposite to the polarity of the source, drain, and gate modulated conductive channel; further comprising an electrical contact region wherein the electrical contact region and the ACS are coextensive.
