Abstract: An electronic device is described that may include an integrated circuit, a volatile memory coupled to the integrated circuit, a non-volatile memory controller coupled to the integrated circuit, and a non-volatile memory coupled to the non-volatile memory controller. In some examples, the integrated circuit is to receive a first instruction at a first frequency via a first storage access physical interface and receive a second instruction at a second frequency via a second storage access physical interface, wherein the first instruction and the second instruction are volatile memory access instructions. The integrated circuit may also be to arbitrate access to the volatile memory based on the first instruction and the second instruction and, responsive to the access to the volatile memory, synchronize contents of the volatile memory with the non-volatile memory via the non-volatile memory controller to maintain data coherency between the volatile memory and the non-volatile memory.
