发明名称 System and method for remapping defective memory locations
摘要 A computer system includes a memory requester that interfaces with a memory module that includes memory portions. An error map that identifies the defective memory portions of the memory module is created and stored in the computer system. Using the error map, a remapping table that maps each of the defective memory portions to a non-defective memory portion in the memory module is created and then stored. In response to receiving from the memory requester a request for access to a requested memory portion of the memory module, a determination is made from the error map whether the requested memory portion is one of the defective memory portions. If the error map indicates that the requested memory portion is one of the defective memory portions, then a determination is made from the remapping table the non-defective memory portion to which the requested memory portion is mapped. The non-defective memory portion is accessed if the error map indicates that the requested memory portion is defective, and the requested memory portion is accessed if the error map does not indicate that the requested memory portion is defective.
