'''Redundant Array of Independent Memory''' ('''RAIM''') is memory system architecture in which memory is made redundant through the use of additional memory modules and techniques such as striping, mirroring, or parity very similar to [[RAID]] used for storage. RAIM goes beyond typical error checking such as ECC and can recover from bit, lane, and even catastrophic memory channel failures. | '''Redundant Array of Independent Memory''' ('''RAIM''') is memory system architecture in which memory is made redundant through the use of additional memory modules and techniques such as striping, mirroring, or parity very similar to [[RAID]] used for storage.

[[IBM]] uses RAIM for their [[z/Architecture]] [[mainframes]] starting with the {{ibm|z196|l=arch}} architecture and most recently in their {{ibm|z14|l=arch}}. IBM uses [[RAID 3]]-style configuration. In those systems the memory controller unit (MCU) reserves an extra memory channel for the RAIM parity. | [[IBM]] uses RAIM for their [[z/Architecture]] [[mainframes]] starting with the {{ibm|z196|l=arch}} architecture and most recently in their {{ibm|z14|l=arch}}.
