ABSTRACT:
Provided is a method and device for reducing lateral movement of charges. The method may include pre-programming at least one memory cell that is in an erased state by applying a pre-programming voltage to the at least one memory cell to have a narrower distribution of threshold voltages than the at least one erased state memory cell and verifying that the pre-programmed memory cell is in the pre-programmed state using a negative effective verifying voltage.
