Abstract: The present technology includes a controller including an allocation manager configured to determine whether a host identification (ID) output from a host is an allocable ID, an address manager configured to perform an allocation operation using the host ID to select logical blocks corresponding to the host ID when the host ID is received from the allocation manager, and output an address of the logical blocks as an allocation address, and a map table component configured to store a map table in which logical block addresses and physical block addresses are respectively mapped, select a logical block address corresponding to the allocation address, and output the physical block address mapped to the selected logical block address, a memory system including the controller, and a method of operating the memory system.

Abstract: A memory system includes a memory device including a plurality of memory blocks, each memory block including memory cells capable of storing multi-bit data, and a controller configured to allocate the plurality of memory blocks for plural zoned namespaces input from an external device and access a memory block allocated for one of the plural zoned namespaces which is input along with a data input/output request. In response to a first request input from the external device, the controller adjusts a number of bits of data stored in a memory cell included in a memory block, which is allocated for at least one zoned namespace among the plural zoned namespaces, and fixes a storage capacity of the at least one zoned namespace.

Abstract: A memory system may include a plurality of nonvolatile memory devices, a first operation unit configured to perform a first operation on target data stored in target nonvolatile memory devices, and one or more second operation units configured to perform second operations. The first operation unit performs the first operation by reading target data and parity data from nonvolatile memory devices not associated with second operations concurrently performed by the second operation units.
