| 1. A buffered memory module comprising:
a downstream driver and a downstream receiver both adapted for connection to a downstream memory bus in a packetized cascaded
interconnect memory subsystem;
an upstream driver and an upstream receiver both adapted for connection to an upstream memory bus in the memory subsystem,
wherein during a test of the memory module the upstream driver is connected to the downstream receiver and the downstream
driver is connected to the upstream receiver;
one or more storage registers;
a microprocessor including instructions for executing the test of the memory module including storing results of the test
in the storage registers; and
a service interface port for receiving service interface signals initiating the execution of the test and for accessing the
storage registers to determine the results of the test.
