ROUTING OF MEMORY TRANSACTIONS

Abstract

An apparatus for processing data is provided comprising persistent memory circuitry, non-persistent memory circuitry and memory controller circuitry. The memory controller circuitry provides two or more memory sub-channels and each memory sub-channel is for routing of memory access transactions for at least one of the persistent memory circuitry and the non-persistent memory circuitry. The memory controller circuitry has channel selection circuitry to detect when there are no non-persistent memory transactions on one of the two or more memory sub-channels and responsive to the detection, is to route any persistent memory transactions to a different one of the two or more memory sub-channels. A memory controller apparatus, a persistent memory Dual In-line Memory Module, a method and computer program are also provided.
