Abstract: In a method of controlling reclaim of a nonvolatile memory device including a plurality of memory blocks, wherein each of the memory blocks includes a plurality of pages, a recovery read operation is performed on first data using an optimal read voltage determined based on the first data, when the first data includes errors which are not correctable, wherein the first data is read from a first page of a first memory block of the memory blocks, and, when the errors of the first data are corrected after the recovery read operation is performed, whether to perform a reclaim of the first page is determined based on threshold voltage distributions of memory cells of the first page, wherein the memory cells are disposed in a region of interest adjacent to the optimal read voltage.

Abstract: There are provided embodiments for providing a motion mode image corresponding to a motion of a target object. In one embodiment, by way of non-limiting example, an ultrasound system comprises: a user input unit configured to receive input information for setting a region of interest on a brightness mode image; and a processing unit configured to form the brightness mode image based on first ultrasound data corresponding to a target object and form vector information of the target object based on second ultrasound data corresponding to the target object, the processing unit being further configured to form a motion mode image including at least one of a brightness motion mode image and a color motion mode image based on the first ultrasound data and the vector information corresponding to the region of interest.
