Abstract:
A split-gate memory cell includes a state transistor possessing a control gate and a floating gate and a selection transistor possessing a selection gate. The split-gate memory cell is programmed by applying, during a programming duration, a first voltage to the control gate, a second voltage to a drain of the state transistor and a third voltage to the selection gate of the selection transistor. The third voltage is transitioned during the programming duration between a first value and a second value greater than the first value.
