Abstract
A memory system having a backplane with a plurality of receiving slots. Each one of the slots has electrical contacts for providing an indication of Such one of the slots. Each one of the slots has a different slot indication. A plurality of memory boards is provided. Each one of the memory boards is plugged into a corresponding one of the slots. Each one of such boards is coupled to the electrical contacts in the corresponding one of the slots to provide a slot signal indicative of the slot indication provided by the electrical contacts. Each one of such boards has: a memory array region; and a switching network for transferring information between a port of the switching network and a memory on such memory boards The transfer is initiated by a director coupled to such port. The director designates a selected one of the plurality of memory boards. The director provides to the switching network a “tag” indicating such designated one of one of the plurality of memory boards having the memory involved in the requested transfer. The switch network includes a memory board checker, for comparing the slot signal with the “tag” for indicating whether the memory boa…
