Abstract: A frequency sensor includes at least one a resistor element and a capacitor. A frequency is detected according to a charging/discharging time to/from the capacitor, thereby realizing a frequency sensor with reduced power consumption and reduced circuit scale. Further, plural resistors and plural capacitors can be provided, along with switches connected to the respective resistors and capacitors. Additionally, a time constant can be adjusted after production, whereby variations in production can be reduced. Furthermore, a self-diagnosis circuit can be included for determining whether the frequency sensor itself operates normally or not. Thus, a highly-reliable frequency sensor can be realized.

Abstract: As a countermeasure against operating an LSI with a frequency out of an allowed range, there is a frequency sensor that generates reference clocks and detects the frequency by counting the reference clocks. In this method, however, power consumption and circuit scale are undesirably increased. So, in the present invention, a resistor element (13) and a capacitor (14) are provided, and a frequency is detected according to a charging/discharging time to/from the capacitor (14), thereby realizing a frequency sensor with reduced power consumption and reduced circuit scale. Further, when plural resistors and plural capacitors are provided and switches are connected to the respective resistors and capacitors, the time constant can be adjusted after production, whereby variations in production can be reduced. Furthermore, when a self-diagnosis circuit for determining whether the frequency sensor itself operates normally or not is provided, a highly-reliable frequency sensor can be realized.

Abstract: An object is to enable the reference level to be generated without the use of a dummy cell in a ferroelectric memory device having a single-transistor, single-capacitor memory cell structure. To achieve this object, a P-type MOS transistor is additionally connected between two nodes which are control terminals of a sense amplifier, and an offset is generated in the sense amplifier. To one of the nodes, a sense amplifier control signal is directly input, and to the other node, the sense amplifier control signal is input through the P-type MOS transistor. The offset level of the sense amplifier is set by setting the potential of the offset control signal which is the gate input of the P-type MOS transistor. Consequently, the reference level can be generated without the use of a dummy cell. As a result, a high-speed, high-reliability ferroelectric memory device can be provided.

Abstract: In a single-wire data communication characterized in that a data communication unit time is different in accordance with the polarity of a signal, a communication control time is dependent on a communication data pattern, and hence, the control of the whole system is difficult. A counter for counting a clock continues the counting until a count value thereby obtained reaches a predetermined upper limit value, retains the predetermined upper limit value as the count value until a next pulse is detected in a reception signal after the count value reaches the predetermined upper limit value, and initializes the count value when the next pulse is detected. A data value judger judges a data value depending on whether or not the pulse is detected during a period before the time when the count value reaches the predetermined upper limit value.
