Abstract: A memory system includes a host device including a host controller, and a memory device including a device controller and a non-volatile storage including a purge region and a memory region. The device controller communicates purge information associated with the purge region and including size information of the purge region. The host controller communicates a request for generating a first partition for a first logical unit in the memory region, and communicates a request for generating a second partition for a second logical unit in the purge region in response to the size information of the purge region.
