Provided are a sense amplifier driver and a semiconductor device comprising the same. The method includes dividing the data mask into a plurality of segments, and representing the segments by respective segment codes, each code indicating whether the bits in the respective segment fall entirely outside the selected group, entirely within the selected group, or include the left end or the right end of the group. The aryl group in the arylalkyl moiety is a 5- or 6-membered ring heteroaromatic, preferably 3-pyridinyl and 5-pyrimidinyl moieties, and the alkyl group is typically a C1-4 alkyl. When acquiring partial data including a chromatic color, then the converting section converts partial data acquired thereafter into the multi-color converted data. The control intervals may be adjusted based on the particular application. The plenum and each of the air ducts at least are made of synthetic material, preferably capable of being molded.
