Abstract
Various embodiments of systems and methods for performing write cache mirroring may involve accessing different mapped regions within a memory. The memory controller may automatically mirror write requests to another memory. Write requests targeting one mapped region may be verified such that local completion of the write indicates that the mirrored write has also completed. Write requests targeting another mapped region may be unverified. Unverified writes may be verified by performance of a verified write.
