Abstract:
A method for programming a split gate memory cell comprises the following steps. First, a split gate memory cell formed on a semiconductor substrate of a first conductive type, e.g., p-type, is provided. The split gate memory cell has two bitlines of a second conductive type, e.g., n-type, a select gate, a floating gate, a wordline and a dielectric layer deposited between the floating gate and the semiconductor substrate, wherein the select gate and floating gate are transversely disposed between the two bitlines, the wordline is above the select gate and floating gate. Second, a positive voltage is applied to the wordline so as to turn on the floating gate, and a negative voltage is applied to the bitline next to the floating gate, whereby a bias voltage across the tunnel dielectric layer is generated for programming, that is, the so called F-N programming.
