  • Patent number: 5352935
    Abstract: A semiconductor integrated circuit device has a first internal voltage controlling circuit which lowers an external power source voltage and produces a predetermined internal power source voltage. The device further has a second internal voltage controlling circuit formed by an internal-voltage drop detection circuit for detecting the lowering of the internal power source voltage from a predetermined reference voltage and a switching circuit for causing the external power source voltage to be directly connected to an internal voltage output terminal based on an output from the internal-voltage drop detection circuit. The internal power source voltage is maintained close to the required value thereby preventing a deterioration of circuit performance even when the external power source voltage drops close to the internal power source voltage.

  • Patent number: 5319302
    Abstract: A semiconductor integrated circuit device is equipped with an internal power source unit for distributing an internal power voltage level between component circuitries, and the internal power voltage level is regulated to a variable reference voltage level, wherein a first main voltage regulator regulates the variable reference voltage level to a primary reference voltage level before reaching a threshold voltage level; however, after the primary reference voltage level becomes lower than the threshold voltage level, a latching circuit supplies an activation signal to a second main voltage regulator, and the second main voltage regulator regulates the variable reference voltage level to a secondary reference voltage level so that the second main voltage regulator continuously controls the variable voltage level without any abrupt transition, thereby allowing the internal power source unit to adjust the internal power voltage level to an arbitrary point.

  • Patent number: 5270584
    Abstract: A semiconductor integrated circuit which comprises a detection circuit for detecting a voltage of a semiconductor substrate and a negative voltage generating circuit for generating a negative voltage to be supplied to the substrate in accordance with an output signal of the detection circuit. The detection circuit includes a first P-channel MOS transistor having a gate connected to a ground potential, a source connected to a power source and a drain connected to a node coupled to the detection circuit, and a second P-channel MOS transistor having a gate connected to the substrate, a source connected to the node and a drain connected to ground. Current does not flow from the external power source to the substrate, so that, even if the negative voltage generating circuit does not have its electric current supplying capacity increased, the voltage of the substrate can be detected.

  • Patent number: 5191235
    Abstract: A node potential V1 which is obtained by the division of an internal reference potential and a substrate potential and another node potential V2 which is obtained by the division of the internal reference potential and the ground potential are compared with each other by a current-mirror amplifier. The initial setting of the above two node potentials (V1 and V2) is made as V1>V2. When the substrate potential becomes large in its absolute value, the node potential V1 falls following such change and, when it reaches a predetermined substrate potential, the potentials result in V1<V2. Then, a true output node of the current-mirror amplifier outputs an output of a largely inverted output level which is further amplified by at least one inverter. The semiconductor integrated circuit device is capable of detecting the predetermined substrate potential even if there exist variations in the threshold values in MOS transistors concerned in the fabricating process.
