Abstract: An apparatus may include a memory device, a memory controller, or both that can communicate via memory standard interfaces. However, the memory device may have physical memory that does not comply with the memory standard by itself. Disclosed herein are solutions that allow various non-standard types of memory, or emerging memory, to be utilized via a host, microprocessor, or memory controller that implements the interface standard. For example, by utilizing a command converter at the microprocessor and a tunneling register at the memory device, a microprocessor can send commands to the memory device by writing them to the tunneling register, which can then be processed at the memory device for operations to be performed with the non-standard or emerging memory.
