摘要： By supplying a clock signal from an OSC to four stages of boosting circuit units connected in series, the boosting circuit units are rendered active. A delay element is inserted in the line of the clock signal to prevent all the boosting circuit units from being rendered active at the same time by one clock signal. Since the boosting circuit unit is rendered active one by one by the provision of the delay element, current congregation from the power supply potential at the circuit element connected closest to the input terminal of the boosting circuit unit of the first stage can be prevented. Thus, a boosting circuit of a high boosting efficiency is achieved.

摘要： When a state of outputting a third power supply potential to an output node is switched to a state of outputting a second power supply potential, connection between a supply unit of the second power supply potential and the output node is made through a first P-channel MOSFET. Further, when the first P-channel MOSFET is turned off, i.e., when the third power supply potential is output to the output node, the third power supply potential is also applied to a gate of the first P-channel MOSFET. Therefore, even when the potential of the output node rises to the third power supply potential, this transistor is not turned on. Thus, the second power supply potential and the output node are appropriately and electrically isolated from each other. The circuit can be used with a flash memory to prevent over programming.

摘要： A power terminal is connected to a DC power source. A differential amplifier has primary and secondary input terminals and an output terminal, and a device applies a reference voltage to the secondary input terminal of the differential amplifier. A phase inverter has an input terminal connected to the output terminal of the differential amplifier and has primary and secondary output terminals that output two output signals of opposite phase. A push-pull drive circuit has primary and secondary input terminals connected to the primary and secondary output terminals of the phase inverter, and has primary and secondary output terminals connected to a switching element that alternately turns on and off by being driven by the two output signals of opposite phase that are provided from the output terminals of the phase inverter. An autotransformer has a tap connected to the power terminal and taps, provided at both sides of the tap connected to the power terminal, that are connected to the primary and secondary output terminals at the push-pull drive circuit, respectively. A capacitive load may be connected at both sides of the autotransformer. A positive feedback path connects one terminal of the autotransformer to the primary input terminal of the differential amplifier, and a sinusoidal AC voltage is applied to the capacitive load. A duty ratio conversion circuit automatically changes the duty ratio of drive signals for the push-pull drive circuit according to the resonance frequency that is determined by the inductance of the autotransformer and the capacitance of the capacitive load. The duty ratio conversion circuit is connected between the phase inverter and the push-pull drive circuit.

摘要： Each match line is connected to a plurality of CAM cells constituting a CAM array. The respective CAM cells store data applied through a bit line and an inverted-bit line in its data storage portion when selected by a word line. The stored data are applied to a data comparison portion to be compared with retrieval data applied through the bit line and the inverted-bit line, thereby detecting match or mismatch therebetween. A comparison result of the data comparison portion is first stored in a capacitance element in the form of charge. In order to prevent escape of the information stored in the capacitance element, a blocking means blocks a part of a charge and discharge path for the capacitance element. A charge transfer means provided between the capacitance element and the match line transfers a certain amount of charge from either one to the other when information of mismatch is stored in the capacitance element. This causes fluctuation of charge potential on the match line. The fluctuation of potential on the match line depends on the number of mismatched CAM cells out of a plurality of CAM cells connected to the match line. Therefore, detection of potential on the match line permits detecting the number of mismatched CAM cells.
