A nonvolatile memory cell is constructed using a floating-gate (FG) pFET
Readout Transistor (RT) having its source tied to a power source (Vdd)
and its drain providing a current which can be sensed to determine a cell
state. The gate of the RT provides for charge/information storage. A
control capacitor structure (CCS) having terminals coupled to a first
voltage source and the FG and a tunneling capacitor structure (TCS)
having terminals coupled to a second voltage source and the FG are
utilized in each embodiment. The CCS has much more capacitance than the
TCS. Manipulation of the voltages applied to the first voltage source and
second voltage source (and Vdd) controls an electric field across the CCS
and pFET dielectrics and thus Fowler-Nordheim tunneling of electrons onto
and off of the FG, thus controlling the charge on the FG and the
information stored thereon.
