Patent ID: 8806103

Claim:
A system comprising: a distributed memory system; an interleave system to determine a target interleave for at least a selected portion of the distributed memory system; a mapping system to: provide memory location information to identify a distribution of memory in the distributed memory system corresponding to the target interleave; and a migration system associated with the interleave system to: in response to a stimulus to cause migration of data, set status indicators for respective first blocks of data in the selected portion for temporarily preventing access to the first blocks; in response to the set status indicators, temporarily prevent access to the first blocks of data in the selected portion while allowing access to second blocks of data that are not part of the selected portion; while access to the first blocks of data is temporarily prevented, migrate the first blocks of data from first interleaved memory locations of the distributed memory system to second interleaved memory locations of the distributed memory system to implement the target interleave in an absence of a system boot process; and individually reset the status indicator for each respective one of the first blocks of data in response to the respective first block of data having been migrated to a corresponding one of the second interleaved memory locations.
