Examples disclosed herein relate to updating memory management information to boot an electronic device from a reduced power mode. In one implementation, prior to entering a reduced power mode, an electronic device creates a snapshot of instructions in a logically volatile partition of a partitioned persistent memory and manage the snapshot as a logically persistent partition. Prior to entering a resume mode, the electronic device updates memory management information to remap a portion of the partitioned memory resource including the snapshot to be managed as a logically volatile partition. The electronic device may resume execution from the snapshot.
