Abstract
A nonvolatile memory cell includes first and second MOS transistors, such as a PMOS transistor and NMOS transistor in a CMOS cell. One of the two transistors provides a floating gate for storing data while the other transistor is provided with a control gate for selecting the memory cell, and is connected with a bit line for reading data stored in the cell. The nonvolatile memory cell may be integrated into a logic device, such as a CMOS gate array, using PMOS and NMOS transistor cells formed in the gate array. In that case, the nonvolatile memory cell may be fabricated in a logic device with the standard processes used to produce the logic device.
