Arrangement for determining the configuration of a memory utilizing dedicated control devices and dedicated control lines

摘要

A memory configuration system including least one of plural control lines and address lines from a memory controller to attached memory may be used as a capacity indicating line, a presence indicating line, and/or a memory type indicating line. With the assistance of coding circuitry dedicated to each mounting region, capacity, presence, and type information for the attached memory module(s) may be communicated via their respective lines. This information is used by the controller to establish a memory configuration.
