Abstract
The preferred embodiments described herein provide a method and system for increasing programming bandwidth in a non-volatile memory device. In one preferred embodiment, a memory device is provided with a plurality of bits to be stored in a respective plurality of memory cells along a wordline. Some of the bits represent a programmed state, and others represent an un-programmed state. The duration of the programming pulse applied to the wordline is determined by the number of bits that represent the programmed state. In another preferred embodiment, the plurality of bits to be stored in the memory device comprises a first set of bits representing a modification to the stored data and a second set of bits representing an un-programmed state. Other preferred embodiments are provided, and each of the preferred embodiments can be used alone or in combination with one another.
