WebThe FAMOS transistor is used as a NVM cell by injecting charge onto the floating gate. Hot electrons transport through the insulating oxide onto the floating gate due to a large electric field from the control gate. The floating gate repels any further injected charge when the charge on the floating gate is saturated. WebNAND flash memories are based on MOSFET transistors with an additional gate called the floating gate. This video explores how these transistors are programmed, erased and …
