Abstract

According to certain aspects, a memory module is coupled to a memory controller of a host computer system via an interface. The interface includes data, address and control signal pins and an output pin in addition to the data, address and control signal pins. The memory module receives a first command from the memory controller via the address and control signal pins, and enters a first mode in response to the first command. The memory module in the first mode responds to at least one initialization sequence, and sends a first output signal via the output pin to indicate a status of the at least one initialization sequence to the memory controller. The memory module enters a second mode in which the memory module performs memory operations including memory read/write operations according to an industry standard. During the read/write operations, the memory module communicates data with the memory controller via the data signal pins in response to second memory commands received via the address and control signal pins. The memory module may output a second output signal related to the read/write operations via the output pin.
