Classification: CPC G | IPC G

Claim 0:
1. A method for programming a memory system, the method comprising:
defining a programming parameter to form a first pre-charge voltage for word lines in a predetermined word line zone and to form a second pre-charge voltage different from the first pre-charge voltage for word lines outside of the predetermined word line zone;
selecting a word line;
in response to the word line being within the predetermined word line zone, applying the first pre-charge voltage;
in response to the word line being outside the predetermined word line zone, applying the second pre-charge voltage,
wherein the first pre-charge voltage comprises a first cell source voltage, and the second pre-charge voltage comprises a second cell source voltage that is less than the first cell source voltage; and
applying a programming voltage to the word line, wherein the programming voltage is less than the first cell source voltage.
