Abstract
A memory system with at least one namespace includes a memory device and a controller. The memory device includes a plurality of single-level cell (SLC) buffers and a plurality of memory blocks, wherein each memory block includes a plurality of memory cells, each memory cell storing multi-bit data, and is allocated for a respective one of a plurality of zones, wherein each of the at least one namespace is divided by at least some of the plurality of zones. The controller is configured to receive a program request related to at least one application program executed by a host, to determine at least one zone designated by the at least one application program as an open state, and to control the memory device to perform a program operation on at least one memory block allocated for an open state zone.
