Abstract
Systems, methods, and computer programs are disclosed for kernel masking dynamic random access memory (DRAM) defects. One such method comprises: detecting and correcting a single-bit error associated with a physical address in a dynamic random access memory (DRAM); receiving error data associated with the physical address from the DRAM; storing the received error data in a failed address table located in a non-volatile memory; and retiring a kernel page corresponding to the physical address if a number of errors associated with the physical address exceeds an error count threshold.
