Abstract
A memory module includes a plurality of memory chips on the module; first logic for configuring the memory module to operate in a selectable mode; second logic for storing initial presence detect (PD) data; and third logic for storing modified PD data that corresponds to a requested mode of operation of the memory module received from a system controller. The system checks the first logic to see if the mode is compatible with the system mode. If not, different PD data is written to and read from the third logic successively until a compatible mode is found or the available PD data is exhausted.
