Abstract
In one embodiment, an apparatus includes: a first memory controller to control access to a first memory, the first memory controller including a memory mirroring circuit, in response to a memory write request from a first processor socket for which the first memory comprises a primary memory region, to cause data associated with the memory write request to be written to the first memory and to send a shadow memory write request to a second memory to cause the second memory to write the data into a secondary memory region; and a shadow memory table including a plurality of entries each to store an association between a primary memory region and a secondary memory region. The memory mirroring circuit may access the shadow memory table to identify the secondary memory region. Other embodiments are described and claimed.
