Abstract
A system and method is disclosed for detecting errors in memory. A memory subsystem that includes a set of parallel memory channels is disclosed. Data is saved such that a duplicate copy of data is saved to the opposite memory channel according to a horizontal mirroring scheme or a vertical mirroring scheme. A cyclic redundancy code is generated on the basis of the data bits and address bits. The generated cyclic redundancy code and a copy of the cyclic redundancy code are saved to the memory channels according to a horizontal mirroring scheme or a vertical mirroring scheme.
