Abstract:
1. A method of reading data from non-volatile storage, comprising: reading a first non-volatile storage element of a first string of non-volatile storage elements to determine whether said first non-volatile storage element is programmed to at least one predetermined state; reading a second non-volatile storage element of a second string of non-volatile storage elements to determine whether said second non-volatile storage element is programmed to said at least one predetermined state; reading a third non-volatile storage element of a third string of non-volatile storage elements using at least one compensation current and a first sampling period if at least one of said first non-volatile storage element and said second non-volatile storage element is programmed to said at least one predetermined state; and reading said third non-volatile storage element using a second sampling period if said first non-volatile storage element and said second non-volatile storage element are not programmed to said at least one predetermined state.
