Patent ID: 10684980

Abstract:
A system and method for multi-channel communication with dual in-line memory modules (“DIMMs”) is disclosed. The system retrieves information characterizing a plurality of memory channels, each of each is configurable to facilitate data communication between a DIMM and a memory controller with associated memory channel interfaces. Based on the retrieved information, one of the memory channels is designated as the active memory channel, granting the designated memory channel the ability to issue memory requests or transactions to the DIMM. On a periodic or as-needed basis (e.g., when the active memory channel is stalled or nearly stalled), the system determines whether to designate a different of the memory channels as the active memory channel, thereby enabling the newly-designated active memory channel the ability to issue memory requests or transactions to the DIMM. In some embodiments, only one of the memory channels is active at a time for communication with each DIMM.
