AUTOMATIC MEMORY BOARD RECONFIGURATION

摘要

A method for automatically reconfiguring the memory address space of a plurality of memory boards allows varying capacity boards to be arbitrarily assigned to backplane locations without human intervention. By reading from a nonvolatile memory on each memory board, a processor can determine the proper address range to assign each memory board. It can then load the information into the board's configuration register and, if necessary, update the board's nonvolatile memory. Each memory board then uses the addresses of incoming access requests and the contents of its configuration register to determine which memory components are to be accessed.
