ADAPTIVE INITIAL PROGRAM VOLTAGE FOR NON-VOLATILE MEMORY

摘要

When programming a set of non-volatile storage elements using a multi-stage programming process, a series of programming pulses are used for each stage. The magnitude of the initial program pulse for the current stage being performed is dynamically set as a function of the number of program pulses used for the same stage of the multi-stage programming process when programming non-volatile storage elements connected to on one or more previously programmed word lines.

1. A method of programming data into non-volatile storage comprising:
programming non-volatile storage elements connected to a first set of one or more word lines using one or more stages of a multi-stage programming process, the multi-stage programming process includes at least a particular stage and an additional stage; determining a voltage magnitude of an initial program pulse for the particular stage of the multi-stage programming process as a function of number of program pulses applied for the particular stage when the particular stage was used to program the non-volatile storage elements connected to the first set of one or more word lines; and programming non-volatile storage elements connected to a selected word line using the particular stage of the multi-stage programming process with the initial program pulse having the determined voltage magnitude.
