Integrated circuit having memory array including ecc and column redundancy and method of operating the same

Abstract

An integrated circuit device (for example, a logic device or a memory device (such as, a discrete memory device)), including a memory cell array having a plurality of memory cells arranged in a matrix of rows and columns, multiplexer circuitry, coupled to the memory cell array, wherein the multiplexer circuitry includes a plurality of data multiplexers, each data multiplexer having a plurality of inputs, including (i) a first input to receive write data which is representative of data to be written into the memory cells of the memory cell array in response to a write operation, and (ii) a second input to receive read data which is representative of data read from memory cells of the memory cell array, and an associated output to responsively output data from one of the plurality of inputs, and syndrome generation circuitry, coupled to the multiplexer circuitry, to generate: (i) a write data syndrome vector using the write data and (ii) a read data syndrome vector using the read data.
