Abstract: A method for identifying memory regions that contain remapped memory locations is described. The method includes determining, from a number of tracking bits on a memory module controller, whether a memory region comprises a remapped memory location. The method further includes performing a remapped memory operation on the memory region based on the determination, wherein memory within a computing device is divided into a number of memory regions including the memory region.

Abstract: In one example a system includes a memory, and at least one memory controller to: detect a failed first memory location of the memory, remap the failed first location of the memory to a spare second location of the memory based on a pointer stored at the failed first memory location, and wear-level the memory. To wear-level the memory, the memory controller may copy data from the spare second location of the memory to a third location of the memory, and keep the pointer in the failed first memory location.

Abstract: Example implementations relate to memory read requests. For example, an implementation may include tracking progress of an iterative write sequence to write data to a memory element of a memory module. A received read request is detected to be addressed to a memory bank that includes the memory element undergoing the iterative write sequence. Based on the tracked progress, a time is determined to interrupt the iterative write sequence with insertion of the read request. The time aligns between operations of the iterative write sequence and data is returned within a predetermined read latency.

Abstract: A method for encoding data in a memory array is described. The method includes receiving data to be stored in the memory array. The method also includes encoding the data, to generate a number of encoded data versions. The method also includes selecting, based on a number of optimization heuristics, which of a number of data versions to store in the memory array. The number of data versions include the number of encoded data versions and the data. The method also includes indicating, in metadata associated with the data, the selected data version. The method also includes writing the selected data version, the metadata, or combination thereof, to the memory array.
