摘要

Embodiments of the invention provide a method and apparatus for accessing a non-volatile memory controller and a volatile memory via a shared interface. In one embodiment, the method includes selecting one of the non-volatile memory controller and the volatile memory via shared control signals of the shared interface, wherein the shared control signals are issued to the non-volatile memory controller and the volatile memory. The method also includes issuing commands to the selected one of the non-volatile memory controller and the volatile memory via the shared control signals.
