Abstract
A simple method of keeping devices turned off is proposed in addition to low-voltage technology such as sub-1-V technology. That is we need to keep devices in a turned-off state as long as possible when not in use, but we need to turn them on instantly when they are required to perform optimally [1, 2]. We usually do this in daily situations as we are faced by increasing concerns with limited resources, but we also do it for greater efficiency. However, it is not easy to apply this concept to actual IT equipment. Although practical instant ON and OFF functions should be implemented in this approach, they require fundamental revisions to the computing architecture. This predicament also raises the need for an approach to combine power-control and computing technologies (information processing technology), to form a basic technology that will generate social innovation in our daily lives.
