Systems and Methods for Improved Communications in a Nonvolatile Memory System

摘要

Systems and methods are provided for improved communications in a nonvolatile memory (“NVM”) system. The system can toggle between multiple communications channels to provide point-to-point communications between a host device and NVM dies included in the system. The host device can toggle between multiple communications channels that extend to one or more memory controllers of the system, and the memory controllers can toggle between multiple communications channels that extend to the NVM dies. Power islands may be incorporated into the system to electrically isolate system components associated with inactive communications channels.

1. A memory controller comprising:
a plurality of internal interfaces, wherein each of the plurality of internal interfaces is configured to communicate with a respective one of a plurality of memories; a plurality of external interfaces, wherein each of the plurality of external interfaces is configured to communicate with a respective one of a plurality of external communications channels; and a processor coupled to the plurality of internal interfaces and to the plurality of external interfaces, wherein the processor is further configured to:
associate a given internal interface of the plurality of internal interfaces with a given external interface of the plurality of external interfaces; andenable a transfer of data between the given external interface and the associated given internal interface.
