  • Patent number: 6756856
    Abstract: Clock generation circuits for an integrated circuit device are provided including a temperature sensor circuit, the temperatures sensor circuit including a calibration circuit responsive to a temperature coding signal and a temperature sensor. The temperature sensor circuit has a first or test mode state in which a temperature output signal of the temperature sensor circuit is based on a temperature sensor output control signal and a second or normal operating mode state in which the temperature output signal is based on the temperature sensor and the calibration circuit. A clock period controller circuit includes a calibration circuit responsive to a period coding signal. The clock period controller circuit generates a period control signal based on the temperature output signal and the calibration circuit of the clock period controller circuit. A clock generator circuit generates a clock signal based on the period control signal.

  • Publication number: 20020110034
    Abstract: An input-output circuit and a current control circuit of a semiconductor memory device which is insensitive to variations in manufacturing process, in voltage levels of input-output pins, and in temperature, and can prevent undesired effects such as an excess of leakage current during operation in a test mode such as a burn-in test. The current control circuit includes first and second transmitters having CMOS transmission gates, a voltage divider, a comparator, a current control counter, a first resistor connected between a bulk of a PMOS transistor of the first CMOS transmission gate and a DC voltage, and a second resistor connected between a bulk of a PMOS transistor of the second CMOS transmission gate and a DC voltage. The first and second resistors prevent current greater than a predetermined level from leaking even though PN diodes formed in the PMOS transistors of the first and second transmitters are forward biased.
