Patent ID: 8391059

Claim:
A multi-gate metal-oxide-semiconductor (MOS) transistor comprising: a first gate associated with a first body factor, wherein the first gate comprises a first gate electrode for applying a first gate voltage, the first gate electrode being in contact with a first dielectric layer; a second gate associated with a second body factor greater than or equal to the first body factor, wherein the second gate comprises a second gate electrode for applying a second gate voltage, the second gate electrode being in contact with a second dielectric layer; a body of semiconductor material between the first dielectric layer and the second dielectric layer, wherein the semiconductor body has a bandgap and comprises a first channel region located close to the first dielectric layer and a second channel region located close to the second dielectric layer, and wherein the second body factor is sufficient to enable a threshold-voltage-based feedback loop of generation of charge carriers in the body to create a hysteresis window in a variation of drain current with the first gate voltage; a source region having a conductivity type different from a conductivity type of the body; and a drain region having a conductivity type different from the conductivity type of the body.
