ABSTRACT:
A method and apparatus for detecting insertion and removal of memory modules in a computer system using standard connectors is disclosed. A memory controller includes logic to read serial presence bits from memory modules incorporating such serial presence features. In response to system software the memory controller monitors a particular slot connector where a memory module is to be inserted or removed. Changes in the serial presence bits indicate insertion or removal. Each slot connector is further connectable to a memory bus for insertion and removal of memory modules while the computer system is operational.
