Abstract: Error handling for resilient software includes: receiving data indicating a region of resilient memory; detecting an error associated with a region of memory; and preventing raising an exception for the error in response to the region of memory falling within the region of resilient memory by preventing the region of memory as being identified as including the error.

Abstract: Selecting an error correction code type for a memory device includes: selecting, by the memory device in dependence upon predefined selection criteria, one of a plurality of error correction code types and carrying out memory access requests utilizing the selected error correction code type.

Abstract: Providing host-based error detection capabilities in a remote execution device is disclosed. A remote execution device performs a host-offloaded operation that modifies a block of data stored in memory. Metadata is generated locally for the modified of block of data such that the local metadata generation emulates host-based metadata generation. Stored metadata for the block of data is updated with the locally generated metadata for the modified portion of the block of data. When the host performs an integrity check on the modified block of data using the updated metadata, the host does not distinguish between metadata generated by the host and metadata generated in the remote execution device.

Abstract: A memory module includes one or more programmable ECC engines that may be programed by a host processing element with a particular ECC implementation. As used herein, the term “ECC implementation” refers to ECC functionality for performing error detection and subsequent processing, for example using the results of the error detection to perform error correction and to encode corrupted data that cannot be corrected, etc. The approach allows an SoC designer or company to program and reprogram ECC engines in memory modules in a secure manner without having to disclose the particular ECC implementations used by the ECC engines to memory vendors or third parties.

Abstract: Error checking data used in offloaded operations is disclosed. A remote execution device receives a request from a host to store a data block in a memory region. The data block includes data and host-generated error checking information for the data. The remote execution device updates the data block by overwriting the host-generated error checking information with locally generated error checking information for the data. The data block is then stored in the memory region.
