Abstract
In a compute express link (CXL) memory controller system, a system and method to identify memory errors which may require soft package repair or hard package repair to rows of DRAM memory. When data is written to a row of DRAM, the data is immediately and automatically read back and scanned for bit errors. If bit errors are identified, steps are taken to determine if the memory location requires no repair, soft repair, or hard repair. The data is corrected and written back to a new memory location which is memory-mapped to the original location, thus effecting the soft- or hard-repair. The present system and method does not repair the entire row of memory, but only repairs the specific die(s) that exhibit memory error in the row.
