摘要： An example integrated circuit includes a first memory array including a first plurality of data groups, each such data group including a respective plurality of data bits. The integrated circuit also includes a first error detection and correction (ED AC) circuit configured to detect and correct an error in a data group read from the first memory array. The integrated circuit also includes a first scrub circuit configured to access in a sequence each of the first plurality of data groups to correct any detected errors therein. Both the first ED AC circuit and the first scrub circuit include spatially redundant circuitry. The first ED AC circuit and the first scrub circuit may include buried guard ring (BGR) structures, and may include parasitic isolation device (PID) structures. The spatially redundant circuitry may include dual interlocked storage cell (DICE) circuits, and may include temporal filtering circuitry.
