Memory Decoder Providing Optimized Error Detection and Correction for Data Distributed Across Memory Channels - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240103967 titled 'Memory Decoder Providing Optimized Error Detection and Correction for Data Distributed Across Memory Channels
Simplified Explanation
The memory controller in this patent application decodes data blocks encoded by error correction code across multiple channels of a redundant memory system. It then generates a predicted channel mark to identify a likely source of data errors and corrects the data accordingly.
- The memory controller decodes data blocks encoded by error correction code across multiple channels of a redundant memory system.
- It generates a predicted channel mark based on tests of channel-induced syndromes to identify a likely source of data errors.
- The memory controller corrects the data by re-reading and excluding data from the marked channel.

Original Abstract Submitted
a memory controller stores each of a plurality of data blocks encoded by error correction code (ecc) across multiple channels of a redundant memory system. based on receiving, from the memory system, channel data of a fetch operation requesting a data block, the memory controller decodes the channel data and concurrently generates a predicted channel mark based on tests of channel-induced syndromes generated from the channel data. the predicted channel mark identifies a marked channel among the multiple channels as a likely source of data errors. the memory controller determines whether the decoding detects an uncorrectable error in the channel data and, based on determining the decoding detects an uncorrectable error in the channel data, re-reads channel data corresponding to the data block and corrects the re-read channel data by excluding, from decoding, channel data received from the marked channel.
