Abstract
A method for the generation of voltage for the programming or erasure of a non-volatile memory cell is disclosed. Also disclosed is a circuit and a computer readable medium which implement the method. During an operation of programming or erasure in the memory, the slope P of the write voltage ramp is adapted to the number of memory cells to be programmed or erased simultaneously during this operation. This method is particularly useful in the field of non-volatile, electrically erasable and programmable memories.
