ERROR DETECTION, CORRECTION, AND MEDIA MANAGEMENT ON A CXL TYPE 3 DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18169621 titled 'ERROR DETECTION, CORRECTION, AND MEDIA MANAGEMENT ON A CXL TYPE 3 DEVICE

Simplified Explanation

The abstract describes a system and method for identifying memory errors in DRAM memory, which may require soft package repair or hard package repair. Here is a simplified explanation of the patent application:

• Data written to a row of DRAM is immediately read back and scanned for bit errors.
• If bit errors are found, the data is corrected and written back to the same memory location.
• The memory location is re-read, and if bit errors persist, it is marked for repair.
• A historical record of memory errors is reviewed to determine if errors have occurred previously at the same location.
• If yes, the memory location is marked for repair again.

Potential Applications: - Computer memory systems - Data storage devices

Problems Solved: - Identifying and correcting memory errors in DRAM - Ensuring data integrity in memory systems

Benefits: - Improved reliability of memory systems - Enhanced data integrity - Reduced need for manual intervention in error correction

Potential Commercial Applications:

1. 1. 1. Improving Data Storage Systems with Advanced Error Correction Technology

Possible Prior Art: There are existing memory error correction techniques in the field of computer hardware, but this specific method of identifying and repairing memory errors in DRAM rows may be a novel approach.

Unanswered Questions:

1. 1. 1. How does this system handle multiple bit errors in a single memory location?

The patent abstract does not specify how the system deals with multiple bit errors occurring simultaneously in a single memory location.

1. 1. 1. What is the impact of this system on overall system performance?

The abstract does not provide information on how the implementation of this memory error correction system may affect the performance of the memory controller system as a whole.

Original Abstract Submitted

In a 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, the data is corrected and written back to the same memory location. The memory location is re-read. If bit errors are again identified, the memory location is marked for soft or hard repair. If, upon rereading the memory location, additional bit errors are identified, a historical record of memory errors is reviewed to determine if bit errors have occurred previously at the same memory location. If yes, the memory location is again marked for a soft post package repair or a hard post package repair.
