Abstract

The present invention provides a NOR flash memory cell. The NOR flash memory cell includes a first transistor, a second transistor and at least one third transistor. The first transistor has a control terminal, a first terminal and a second terminal. The control terminal used to receive a word line signal and the first terminal used to receive a bit line signal. A gate of the first transistor comprises a silicon-rich nitride layer and an oxide layer, wherein the silicon-rich nitride layer is buried in the oxide layer. A control terminal of the second transistor used to receive a read signal. A second terminal of the second transistor used to transport a source line signal according to the read signal. The third transistor coupled between the first transistor and the bit line signal, and a control terminal of the third transistor receives a midway control signal.
