Patent ID: 7700994

Claim:
A complimentary metal-oxide-silicon (CMOS) integrated circuit (IC) device including a plurality of non-volatile logic cells, each non-volatile logic cell comprising: a polycrystalline silicon floating gate; and means for changing a charge stored on the floating gate from an initial charge value to a final charge value, said means comprising: first means, capacitively coupled to a first region of the floating gate, for changing the charge stored on the floating gate from the initial charge value to an intermediate charge value by inducing Fowler-Nordheim injection between said first means and the first region of the floating gate, the intermediate charge value being between the initial charge value and the final charge value; and second means, disposed adjacent to a second region of the floating gate, for changing the charge stored on the floating gate from the intermediate charge value to the final charge value by inducing Band-to-Band tunneling between said second means and the second region of the floating gate.
