APPARATUS, SYSTEM, AND METHOD FOR A DIRECT INTERFACE BETWEEN A MEMORY CONTROLLER AND NON-VOLATILE MEMORY USING A COMMAND PROTOCOL

摘要

A method for a direct interface between a memory controller 605 and a non-volatile memory controller 712 using a command protocol includes receiving a command from a memory controller 605 to a non-volatile memory controller 712 over a wire interface 707 by way of a command protocol. The memory controller 605 is coupled to one or more processors 602 and the non-volatile memory controller 712, in one embodiment, is coupled to non-volatile memory media 718. The command protocol includes a control path 708 that enables the memory controller 605 to distinguish among different memory modules. The non-volatile memory controller 712 stores data sequentially on the non-volatile memory media 718 to preserve an ordered sequence of memory operations performed on the non-volatile memory media 718. The method includes executing the command within the non-volatile memory controller 712 in response to determining that the non-volatile memory controller 712 is capable of satisfying the command.
