A dual in-line memory module (DIMM) includes a memory storage device having data rows and redundant rows. The DIMM further includes a post-package repair module configured to remap an address within the DIMM physical address space from a data row to a redundant row. A memory controller is configured to determine an exact number of un-remapped redundant rows.

System and method for determining available post-package repair resources

An information handling system includes a processor, a dual in-line memory module (DIMM), and a memory controller coupled to the DIMM. The memory controller provides interrupts to the processor each time a read transaction from the DIMM results in a correctable read error. The processor instantiates a failure predictor to receive the interrupts, accumulate a count of the interrupts, and provide a first error indication when the count exceeds a first error threshold. The failure predictor increments the count each time the predictor receives a particular interrupt and decrements the count in accordance with an error leak rate. The error leak rate has a first value when the DIMM is newer than a first age threshold and has a second value when the DIMM is older than the first age threshold.
