Abstract: A lamp for a vehicle is provided. The lamp for the vehicle includes a lamp component to form a beam pattern that includes a plurality of pattern areas, an image acquisition component to acquire a forward view image of the vehicle at a predetermined period, a recognition component to recognize a front vehicle from the forward view image, and a control component to control a light amount of at least one pattern area that corresponds to the front vehicle among the plurality of pattern areas to form a shadow area. In particular, the control component controls a light amount of at least one pattern area, including a width of the front vehicle and predetermined fixed ranges added to both sides of the front vehicle, among the plurality of pattern areas to form the shadow area.

Abstract: A host device controls a storage device to perform a read operation of a read data unit with respect to selected memory areas. A read latency corresponding to the read operation of the storage device is stored in a read latency table of the host device. A determination is made whether a latency change ratio exceeds a threshold value, based on the read latency stored in the read latency table. The data host requests a data retention operation from the storage device, through a retention command, when the latency change ratio exceeds the threshold value.

Abstract: A storage device includes a nonvolatile memory device and a memory controller. The nonvolatile memory device includes memory blocks divided into a buffer region and a main region. The memory controller controls the nonvolatile memory device to perform a buffer program operation to program externally provided data into the buffer region, a migration program operation to migrate data stored in the storage device to the main region, and a direct program operation to program externally provided data into the main region. The direct program operation is performed when the size of the externally provided data is larger than that of an available programmable region in the buffer region, and the migration program operation is performed to migrate some of the data programmed into the buffer region to the main region after the direct program operation is performed.
