ABSTRACT:
FIELD OF THE INVENTION
This invention relates to the electric and electronic equipment with a clock circuit, a memory circuit and a standby circuit which opens and closes power supply in special condition.
BACKGROUND OF THE INVENTION
Here to fore, we have requested the electric and electronic equipment like a personal computer convenient functions, high speed operations and low consuming power. It is performed by including high integrated IC and exchanging the IC from NMOS to CMOS.
And now, we need higher speed and lower consuming power on standby. But the high speed clock and the loss of transformer circuit interfere this realization.
SUMMARY OF THE INVENTION
This invention is composed of a clock circuit which controls clocks by a CPU, a memory circuit which accesses to an asynchronous memory from the synchronous CPU in high speed, a standby circuit which runs by an AC to DC converter without any transformers and which drives an equipment by a relay circuit and a communication circuit connecting to an external appliance.
