Questions about the Technology

How does the non-blocking exception handling process improve the reliability of memory systems?

The non-blocking exception handling process allows the memory system to continue operations even after a program failure, ensuring that data can be moved to another page and the failed block can be replaced with a spare block. This helps in maintaining the integrity of the data and the overall reliability of the memory system.

What are the potential implications of using uncorrectable data marking in memory systems?

Uncorrectable data marking allows the memory system to distinguish between program failures and uncorrectable errors, ensuring that data integrity is preserved. This feature can help in efficiently managing errors and minimizing data loss in memory systems.

Original Abstract Submitted

Methods, systems, and devices for programming failure handling during data folding are described. A memory system may support a non-blocking exception handling process for handling program failures that occur during folding. For example, if a program failure occurs at a given page, the memory system may mark the failed page as storing uncorrectable data (e.g., associated with an uncorrectable error correction code (UECC) error) rather than as being associated with the program failure. Based on the marking, the memory system may continue the folding operation, allowing the data to be moved to another page of a physical destination block. After the folding operation is complete, the memory system may replace a failed physical destination block that includes the failed page with a spare block and retire the failed physical destination block.
