System and method for controller independent faulty memory replacement

摘要

In accordance with the present disclosure, a system and method for controller independent faulty memory replacement is described. The system includes a system memory component with a system memory component architecture. The system also includes a memory buffer coupled to the system memory component. The memory buffer may include at least one spare memory location corresponding to a faulty memory location of the system memory component. Additionally, the system memory component architecture may receive a read command directed to an address of the system memory component containing the faulty memory location and output, in response to the read command, data corresponding to the address from both the system memory component and the at least one spare memory component.

主权项

1. A system for controller independent faulty memory replacement, comprising:
a memory component; a memory controller communicably coupled to the memory component, wherein the memory controller directs read and write commands to addresses within the memory component; a replacement table accessible by the memory component, wherein the replacement table holds memory component addresses and data bits to be replaced and wherein the replacement table is accessible by the memory component; and a spare memory coupled to the memory component, wherein the spare memory is operable to include a replacement memory location corresponding to the memory component addresses within the memory component containing a faulty memory element and to respond to a read or write command from the memory controller directed to the address within the memory component containing the faulty memory element, and wherein the spare memory includes a faulty memory table for storing memory component addresses.
