Abstract:
A method of operating a non-volatile memory system wherein values stored in some of storage elements of an array of memory elements affect values read from others of the storage elements because of at least electric field coupling between storage elements, comprising:writing into a first group of storage elements a first set of stored values that correspond to a first set of data, thereafter writing into a second group of storage elements different from the first group a second set of stored values that correspond to a second set of data, wherein at least some of the stored second set of values affect values read from at least some of the first group of storage elements because of at least field coupling between them, and altering the first set of stored values written into the first group of storage elements in order to counteract an effect of the second set of stored values on the values read from said at least some of the first group of storage elements because of at least field coupling between them, thereby to facilitate accurate reading of the first set of data from the first group of storage elements.
