Abstract: A system and method for memory error recovery in CXL components is presented. The method includes determining that a memory component has sustained a hard failure in a Cyclic Redundancy Check-Redundant Array of Independent Devices (CRC-RAID) mechanism. The method further includes determining a location of the memory component failure, wherein the CRC-RAID mechanism comprises a plurality of memory components configured as a plurality of stripes and initiates a write operation of user data to a location within a particular stripe, wherein the particular stripe contains a failed memory component. The method includes compensating for the failed memory component, wherein the compensating comprises a plurality of read operations prior to a writing of the user data.

Abstract: There are provided methods and systems for on-ASIC error control coding for verifying the integrity of data from a memory. For example, there is provided a method for encoding data into a beat. The method can be executed by a digital system configured to receive the data and construct the beat. The method includes assembling, by the digital system, a plurality of words consecutively. The plurality of words can include a first set of words in which each word has a length W, where W is the beat width. The plurality of words can further include a second set of words in which each word has a length that is smaller or equal to W. The method can further include constructing a parity word of length W, wherein each bit in the parity word is a parity associated with a distinct word in the first and second set of words. The method further includes adding the parity word to the plurality of words to form the beat.
