Abstract:
1. A method of erasing non-volatile storage, comprising: applying compensation to a portion of a string of non-volatile storage elements to at least partially compensate for a voltage coupled to one or more non-volatile storage elements of said string from at least one transistor of said string, said applying compensation includes applying a first compensation voltage to a first non-volatile storage element of said string and a second compensation voltage to a second non-volatile storage element of said string, said first compensation voltage includes at least one of a different magnitude and a different polarity than said second compensation voltage; applying a third voltage to a third non-volatile storage element of said string, said third voltage includes at least one of a different magnitude and a different polarity than said first compensation voltage, said third voltage includes at least one of a different magnitude and a different polarity than said second compensation voltage; and transferring charge from a floating gate of at least a subset of non-volatile storage elements of said string while applying said compensation in order to erase said string of non-volatile storage elements, said subset of non-volatile storage elements includes said first non-volatile storage element, said second non-volatile storage element and said third non-volatile storage element.
