Abstract:
1. A method of operating a non-volatile memory system, comprising: storing a plurality of data sets in a first non-volatile memory section of the system; for each of the data sets, storing a corresponding signature in a search array, where for each of the data sets the signature is derived from the corresponding data set and is of a smaller size, wherein the search array is of NAND type architecture and the signatures are stored therein oriented along the search array's bit lines; maintaining by the memory system of a correspondence between the location at which the data sets are stored in the first non-volatile memory section and the location at which the corresponding signatures are stored in the search array; receiving a first signature; biasing the word lines of the search array according to the first signature; and determining whether any of the bit lines of the search array conduct in response to said biasing of the word lines.
