Abstract: A virtualized system includes a nonvolatile memory device, a processing circuitry configured to provide a virtualization environment, implement a plurality of virtual units and implement a virtual unit manager. The virtual units operate independently of each other in the virtualization environment and perform a flash translation layer operation inside the virtual units. The flash translation layer operation includes converting a logical block address associated with a storage access operation of the nonvolatile memory device to a physical block address of the nonvolatile memory device. The virtual unit manager controls the virtual units in the virtualization environment.

Abstract: In a method of writing data in a storage device, a data write request is received from a host device. Spatial information is received from a spatial sensor included in the storage device based on the data write request. A logical storage area management table is updated based on the data write request and the spatial information such that target data to be stored is written into a target storage area corresponding to the spatial information among a plurality of logical storage areas. A program command and the target data are transmitted to a nonvolatile memory such that the target data is programmed into a physical storage area in the nonvolatile memory corresponding to the target storage area.
