Title:
ALLOCATION OF POST PACKAGE REPAIR (PPR) RESOURCES BASED ON MEMORY ROW ERROR TYPE CLASSIFICATION
Document Type and Number:
WIPO Patent Application WO/2024/082275
Kind Code:
A1
Abstract:
Allocation of post package repair (PPR) resources based on memory row error type classification. The method executes various system memory tests for dynamic random access memory devices and modules in operable communication with a processor. The methodology performed quickly classifies an error detected at boot-time as either a correctable error (CE) type or an uncorrectable error (UCE) type. A preprogrammed CE threshold (a maximum number of CEs per row) is also employed. The method advantageously only resorts to PPR in the following scenarios: If there is a UCE in the row, then perform PPR to repair the row immediately; and, If there are only CEs in the row, but the number of CE is above a pre-defined threshold, then perform PPR to repair the row immediately.
