The present invention relates to a portable communication device arrangement comprising a main unit and an auxiliary unit. The DRAM includes a plurality of sub-arrays, each having a plurality of memory cells, each of which is coupled with a complementary bit line pair and a word line. The first sampling signal, which is associated with the real sampled output signal, is delayed by one-fourth cycle with respect to the second sampling signal, which is associated with the imaginary sampled output signal. The solvent of the sugar solution used in the production of the complex crystalline sugar is water or a mixture of water and ethanol.
