Abstract
A Bose, Ray-Chaudhuri, Hocquenghem (BCH) decoder is employed in non-volatile memory applications for determining the number of errors and locating the errors in a page of information. The decoder includes a syndrome calculator responsive to a sector of information. The sector includes data and overhead, with the data being organized into data sections and the overhead being organized into overhead sections. The syndrome calculator generates a syndrome for each of the data sections. A root finder is coupled to receive the calculated syndrome and to generate at least two roots. A polynomial calculator responds to the two roots and generates at least two error addresses, each identifying a location in the data wherein the error lies.
