CAPACITY-EXPANDING MEMORY DEVICE

摘要

The invention relates to a device, system, and method for expanding the memory capacity of a memory module. A control unit and memory bank switch are mounted on a memory module to selectively control write and/or read operations to/from memory devices communicatively coupled to the memory bank switch. By selectively routing data to and from the memory devices, a plurality of memory devices may appear as a single memory device to the operating system. That is, the invention expands the addressable memory banks on a module by making two smaller-capacity memory devices emulate a single higher-capacity memory device.
