TECHNIQUE FOR REPAIRING MEMORY MODULES IN DIFFERENT POWER REGIONS

摘要

A reshift unit within a computer system is configured to store repair information associated with random-access memory (RAM) modules that reside in different power regions. When one or more RAM modules in a given power region need to be repaired, the reshift unit identifies a portion of the repair information that is relevant to those RAM modules. The reshift unit then transmits that portion to the RAM modules, thereby repairing those RAM modules. Accordingly, RAM modules in a given power region can be repaired independently of RAM modules in other power regions. Advantageously, RAM modules can be repaired between cold boots without implementing the slow repair procedure performed by the fuse block during cold boot.

1. A computer-implemented method for repairing a memory module, the method comprising:
receiving repair information associated with a plurality of memory modules; identifying a first memory module included in the plurality of memory modules that needs to be repaired; identifying a first portion of the repair information that is associated with the first memory module; and transmitting the first portion of the repair information to the first memory module in order to repair the first memory module.
