    摘要: The clock-generating circuit for generating a clock signal, includes a ring oscillator having an odd number of inverters connected in a ring configuration. The ring oscillator is activated to generate a clock signal when an activating signal is at a first level and is de-activated to cease generation of the clock signal when the activating signal is at a second level. A latch circuit is connected to an output node of the ring oscillator, and holds a level of the output node of the ring oscillator in response to transition of the activating signal from the first level to the second level. When the activating signal is lowered from the H level to the L level, the level of the clock signal is latched such that generation of a glitch in the clock signal will be prevented from occurring.

    摘要: A boosting circuit is provided with a voltage detection circuit, first through fourth oscillators, and first through fourth charge pump circuits. The voltage detection circuit compares each of the first through fourth voltages obtained by dividing a boosted voltage with a reference voltage, and generates first through fourth activation signals. The first through fourth oscillators output pulse signals at first through fourth frequencies, respectively, as first through fourth drive signals. The first through fourth charge pump circuits operate in response to the first through fourth drive signals, respectively, and boost the boosted voltage. Accordingly, it is possible to provide a stable boosted voltage, with suppressing over shoot and under shoot with respect to the boosted voltage as a target.

    摘要: A conductor line is placed at a layer overlying an input protection circuit electrically coupled to a pad such that the conductor line covers at least a part of the input protection circuit. The conductor line having a sufficiently large width disperses and absorbs the heat generated from the input protection circuit. Since the input protection circuit and the conductor line have a region overlapping with each other in the layout of plan view, an area for layout of the input protection circuit on a chip can be reduced effectively, and prevention of a destruction of the protection circuit due to the heat as well as an improvement of a resistance to the surge can be obtained.

A storage transistor has impurity diffusion regions, a channel formation region, a charge accumulation node, a gate oxide film, and a gate electrode. The gate electrode is connected to a gate line and the impurity diffusion region is connected to a source line. The storage transistor creates a state where holes are accumulated in the charge accumulation node and a state where the holes are not accumulated in the charge accumulation node to thereby store data “1” and data “0”, respectively. An access transistor has impurity diffusion regions, a channel formation region, a gate oxide film, and a gate electrode. The impurity diffusion region is connected to a bit line.
