An object of the present invention is to provide a power amplification device having high power efficiency for an input signal even in a power region in a large back-off. Certain of these compounds also inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by VLA-4. This encryption key E is taken from a table of encryption keyhash pairs which have been provided to the DRM Controller by an external authority such as the content rights holder. The first input of the first multiplexer and the first input of the second multiplexer are coupled to different one of the pair of global bit-lines.
