摘要：
A random number generating circuit receives as input a first digital random number signal generated at a first generating rate and produces as output a second digital random number signal having a second generating rate that is twice as high as the first generating rate. A semiconductor integrated circuit, an IC card and an information terminal device comprising the random number circuit is provided.
