Program verify for non-volatile storage

摘要

A non-volatile storage system includes a plurality of non-volatile storage elements arranged in two dimensional or three dimensional structures. The system applies programming to the non-volatile storage elements and performs verification of the programming. The verification includes performing a multi-strobe sensing operation to test for multiple data states while applying a common word line voltage.

1. A method of operating non-volatile storage, comprising:
applying programming to a non-volatile storage element coupled to a selected word line; and verifying the programming of the non-volatile storage element, including performing a multi-strobe sensing operation to test for at least two different data states while applying a same word line voltage to the selected word line for the multi-strobe sensing operation.
