Some example embodiments include methods of operating a wireless communication device supporting carrier aggregation, the methods include allocating a memory of a plurality of memories to each of a plurality of component carriers based on a memory allocation priority; determining a demodulation priority for each of the plurality of component carriers based on one of a size of each memory allocated to each of the plurality of component carriers, and the memory allocation priority; and demodulating signals received via the plurality of component carriers based on the demodulation priority.

Wireless communication device including memory de-allocator for efficient memory usage and method of operating the same

A vertical memory device may include a conductive pattern structure, a pad structure, a plurality of channel structures, a plurality of first dummy structures and a plurality of second dummy structures. The conductive pattern structure may be in a first region of a substrate, and may extend in a first direction. The pad structure may be in a second region of the substrate adjacent to each of opposite sides of the first region of the substrate, and may contact a side of the conductive pattern structure. The channel structures may extend through the conductive pattern structure, and may be regularly arranged on the substrate. The first dummy structures may extend through the conductive pattern structure, and may be disposed in a portion of the first region of the substrate adjacent to the second region thereof. The second dummy structures may extend through the pad structure on the substrate. Each of the channel structures may have a first width in the first direction, and each of the first dummy structures may have a second width in the first direction greater than the first width.

Vertical semiconductor devices

A chipset is provided. The chipset is configured to detect an interference characteristic of a neighbor cell corresponding to groups and perform an interference whitening operation based on the interference characteristic. The groups are generated by dividing a time interval occupied by a first reference signal region by dividing a frequency band occupied by the first reference signal region, or by dividing a time interval occupied by a second reference signal region. A frequency band occupied by the second reference signal region is wider than the frequency band occupied by the first reference signal region.
