Abstract:
A memory controller performs a mirror copy function in a way that allows processor accesses to memory to continue during the mirror copy operations that make up the mirror copy function. Data integrity of mirror copy operations is assured by protocols set up in the memory controller. The result is a memory controller that performs a mirror copy function in a way that allows normal processor accesses to memory to be interleaved with mirror copy operations, thereby minimizing the impact on system performance of executing the mirror copy function.
