ABSTRACT:
A technique for handling errors in a memory system. Specifically, a new dual mode ECC algorithm is provided to detect errors in memory devices. Further, an XOR memory engine is provided to correct the errors detected in the dual mode ECC algorithm. Depending on the mode of operation of the dual mode ECC algorithm and the error type (single-bit or multi-bit), errors may be corrected using ECC techniques. If X16 or X32 memory devices are implemented, a technique for striping the data from each memory device is implemented to detect errors in the X16 and X32 devices.
