Abstract
A memory module includes: a non-volatile memory; and an asynchronous memory interface to interface with a memory controller. The asynchronous memory interface may use repurposed pins of a double data rate (DDR) memory channel to send an asynchronous data to the memory controller. The asynchronous data may be device feedback indicating a status of the non-volatile memory.
Claims25
A memory module comprising:
- a non-volatile memory;
- and
- an asynchronous memory interface to interface with a memory controller,
- wherein the asynchronous memory interface uses repurposed pins of a double data rate (DDR) memory channel to send an asynchronous data to the memory controller.

A system comprising:
- a memory controller;
- a memory module comprising a non-volatile memory;
- and
- an asynchronous memory interface between the memory controller and the memory module,
- wherein the asynchronous memory interface uses repurposed pins of a DDR memory channel to send device feedback of the memory module to the memory controller.
2 more elements
