A semiconductor structure includes a first strap cell, a first read port, and a first VSS terminal. The wiring route determining apparatus or the like independently weights the distance between the blocks vertically and horizontally and determines a wiring route taking into account the distance which is weighted. A fan unit is selectively positioned adjacent to a first side of the heat exchanger. The substrates are coated such that the water vapour permeation sites are not blocked by the coating to maintain the desired breathability. Programming and verification is achieved at high speed and with minimal power consumption using a novel programverify algorithm for anti-fuse memory. The second electrode is electrically coupled with the second type semiconductor layer.
