Abstract

A non-volatile memory cell includes a floating gate transistor having a floating gate. A method for operating the non-volatile memory cell includes, during a program operation, performing an initial program searching operation to identify a first initial value of a threshold voltage of the floating gate transistor, coupling the floating gate of the floating gate transistor to a first program voltage to raise the threshold voltage of the floating gate transistor, performing a program searching operation to identify a first variation of the threshold voltage, generating a second program voltage according to the first variation of the threshold voltage, and coupling the floating gate of the floating gate transistor to the second program voltage to raise the threshold voltage of the floating gate transistor.
