Abstract
A system for implementing a memory subsystem command interface, the system including a cascaded interconnect system including one or more memory modules, a memory controller and a memory bus. The memory controller generates a data frame that includes a plurality of commands. The memory controller and the memory module are interconnected by a packetized multi-transfer interface via the memory bus and the frame is transmitted to the memory modules via the memory bus.
Claims13
A cascaded interconnect system comprising:
- one or more memory modules;
- a memory controller for generating data frames that include a plurality of commands, each data frame comprised of the same number of transfers;
- and
- a memory bus, wherein the memory controller and the memory modules are interconnected by a packetized multi-transfer interface via the memory bus and wherein the frames are transmitted to the memory modules via the memory bus.
A storage medium encoded with machine readable computer program code for providing a memory subsystem command interface, the storage medium including instructions for causing a computer to implement a method comprising:
- receiving a data frame including a plurality of commands at a current memory module, wherein the current memory module is included in a cascaded interconnect system that includes a memory controller and one or more memory modules that are interconnected via a memory bus, and each data frame is comprised of the same number of transfers;
- and
- executing one or more of the commands in response to the one or more commands being directed to the current memory module.
