1. A method of operating a computing system, the method comprising:
defining a zoned namespace for non-volatile memory (NVM) of a memory device of the computing system, the zoned namespace including multiple NVM zones of multiple non-overlapping logical block addresses (LBAs) of the NVM;
mapping persistence logging (PLOG) zones to the NVM zones, a PLOG zone including a PLOG ID identifying the PLOG zone and a PLOG size indicating a number of one or more NVM zones included in the PLOG zone; and
performing a PLOG-specific access operation on a PLOG zone of the NVM in response to a PLOG-specific command received from a host device of the computing system.
