1. INTRODUCTION
Single electron memory is an ultimate device that can store one-bit information by charging a single electron. This device is one of promising candidates for basic elements of future electronics. Advantages of the single-electron devices are as follows. Good scalability is the strong incentive to explore the possibility of this device. Because the operating principle relies simply on the Coulomb repulsion among electrons, single-electron devices are anticipated to operate even with very small physical dimensions, such as atomic scale, making ultralarge scale integration possible. Another advantage is its ultra low power operation, simply because they use very small number of electrons to accomplish basic operations. Another advantage may be faster operation. In conventional devices, more than 100 000 electrons are charged/discharged for a basic digital operation. In single electron memory, only a few electrons are transferred, therefore, the process might be faster than those of conventional devices...
