A method and apparatus to detect, initialize and isolate a non-operating memory module in a system without physically removing the memory module from the system is provided. The memory module includes a power management integrated circuit to provide power to a memory integrated circuit on the memory module. During initialization of the memory module, if an error log stored in a non-volatile memory in the memory module indicates a fatal error condition from a prior power cycle, the memory module is electrically isolated.

Initialization and power fail isolation of a memory module in a system

A memory controller includes a sensor poller and a proportional integral controller (PIC) coupled to the sensor poller. The sensor poller is to obtain a temperature and a power of a memory module (MM) operated by the controller, and the PIC is to: dynamically set at least one bandwidth limit for the MM, based, at least in part, on a relationship between a temperature of the MM, a power of the MM and a bandwidth of the MM. The dynamically set bandwidth limit defines the power of the MM at which the MM operates for a predetermined temperature limit. A system includes a memory controller and a dual in-line memory module (DIMM) operated by it.

Power-based dynamic adjustment of memory module bandwidth

In one embodiment, an apparatus comprises a first connector to couple to a connector of a memory card, the memory card comprising a first sense node to sense a supply voltage at a first location of the memory card, the first connector comprising a voltage supply pin; a ground pin; and a sense pin to couple to the first sense node; a first sense line to couple to the first sense node through the sense pin; and a voltage regulator coupled to the first sense line, the voltage regulator to provide the supply voltage based on feedback received from the first sense node of the memory card via the first sense line.
