摘要:
There are provided a voltage level control circuit with a reduced power consumption and a method of controlling the same. When a signal “A” is in a “L” level and a signal PL entered from the outside of the voltage level control circuit becomes “H” level, a latch signal La outputted from a latch (11) becomes “H” level, whereby NFETs (14, 17, 24) turn ON. A voltage dividing circuit comprising resistances (12, 13) and current mirror differential amplifiers (20, 27) are placed in active states to output “H” as a signal A which controls a boost voltage Vbt (word line driving voltage. As the boost voltage Vbt is increased and reaches to a reference voltage Vref2, a voltage V2 becomes “H”, whereby the signal A becomes “L”. After the signal A become “L”, the latch (11) is made through. At this time, the signal PL is “L”, the latch signal La outputted from the latch (11) becomes “L”, whereby the NFETs (14, 7, 24) turn OFF. As described here, the NFETs (14, 7, 24) is kept OFF in the other time period than when needed, in order to reduce the power consumption.
摘要:
In the event that job data to be transmitted from a first information processing device is first-type job data, but a second information processing device is not ready to immediately perform processing of the job data, the first information processing device can be inhibited from transmission of the job data. In the event that job data to be transmitted from the first information processing device is the first-type job data and the second information processing device is ready to immediately perform processing of the job data immediately, the first information processing device is permitted to transmit the job data. Thus, various types of problems or user demands that can occur in a situation in which a user accidentally or inadvertently transmits critical data such as secret documents or private documents or the like to a device which cannot process the job data immediately are handled as much as possible.
摘要:
A device testing apparatus including a connection terminal to which an electronic device under test is detachably attached, a pusher for pushing the electronic device in the direction of the connection terminal so as to connect the electronic device to the connection terminal, and a cooling unit for cooling the electronic device. As the cooling unit, an element cooling the device using electricity is for example used. The cooling unit includes a cooling medium blower for blowing a cooling medium around the electronic device and heat exchange projections or depressions for raising the cooling efficiency by blowing a cooling medium. In the device testing apparatus, even if the electronic device generates heat on its own during testing, the electronic device is cooled through the pusher, connection terminals, or socket, so the effect of the heat generated by the electronic device is canceled out and the electronic device can be tested at the predetermined temperature as prescribed in the specification.
