Abstract
A memory system includes a first memory module and a second memory module. A memory controller is coupled to the first and second memory modules and reads configuration information from the first and second memory modules using a memory channel. The controller also configures a switch coupled between the controller and one of the memory modules to communicate using either a chip select line or a memory address line.
Claims20
A memory system comprising:
- a first memory module;
- a second memory module;
- at least one switch coupled to at least one of the first memory module and the second memory module;
- and
- a memory controller coupled to each of the first memory module and the second memory module, wherein the memory controller is coupled to at least one of the first memory module and the second memory module through the least one switch via a plurality of signal lines, and wherein the memory controller is operable to determine a memory module type for at least one of the first memory module and the second memory module, and configure the at least one switch based on at least one memory module type requirement and the signaling needs of at least one of the first memory module and the second memory module to allow communication between the memory controller and at least one of the first memory module and the second memory module using at least one of the plurality of signals lines.

An information handling system (IHS) comprising:
- a processor;
- and
- a memory system coupled to the processor, wherein the memory system includes:
- a first memory module;
- a memory controller;
- and
- a switch coupling the first memory module to the memory controller via a plurality of signal lines;
- wherein the memory controller is operable determine a memory module type for the first memory module and configure the switch based on at least one memory module type requirement and the signaling needs of the first memory module to allow communication between the memory controller and the first memory module using at least one of the plurality of signal lines.

A method comprising:
- providing a memory controller coupled to a first memory module, wherein at least one switch is coupled between the memory controller and the first memory module by a plurality of signal lines;
- determining a memory module type for the first memory module;
- and
- configuring the at least one switch based on at least one memory module type requirement and the signaling needs of the first memory module to allow communication between the memory controller and the first memory module using at least one of the plurality of signaling lines.
