Abstract
An expandable memory system including a central memory controller and one or more plug-in memory modules, each memory module having an on-board memory module controller coupled in a serial network architecture which forms a memory command link Each memory module controller is serially linked to the central memory controller. The memory system is automatically configured by the central controller, each memory module in the system is assigned a base address, in turn, to define a contiguous memory space without user intervention or the requirement to physically reset switches. The memory system includes the capability to disable and bypass bad memory modules and reassign memory addresses without leaving useable memory unallocated.
