A semiconductor device includes an on-chip termination circuit, a reference voltage generator, and an input buffer. The on-chip termination circuit generates a variable resistance to an input signal based on at least one code signal. The reference voltage generator generates a reference voltage based on the code signal. The input buffer generates an internal signal based on the input signal from the on-chip terminal circuit and based on the reference voltage.

Semiconductor devices with reference voltage generators and termination circuits configured to reduce termination mismatch

Integrated circuit devices include data inversion circuits therein that are configured to evaluate at least first and second ordered groups of input data in parallel with an ordered group of output data previously generated by the data inversion circuit. The data inversion circuit is further configured to generate inverted versions of the first and second ordered groups of input data whenever a number of bit differences between the first ordered group of input data and the ordered group of output data is greater than one-half a size of the first ordered group of input data and a number of bit differences between the second ordered group of input data and the inverted version of the first ordered group of input data is greater than one-half a size of the second ordered group of input data, respectively.

Integrated circuit devices having data inversion circuits therein that reduce simultaneous switching noise and support interleaving of parallel data

Devices, circuits and methods for dual voltage generation using a single charge pump. The dual voltages can be the same or different, as they are for two different components of a device. An oscillator generates an oscillating signal, and a charge pump generates a pumping voltage at a pumping node responsive to the oscillating signal. A first switching circuit is coupled to the pumping node, and outputs from the pumping voltage a first voltage to the first component. A second switching circuit is coupled to the pumping node, and outputs from the pumping voltage a second voltage to the second component. The first and second output voltages may optionally be sensed. The oscillator may be triggered and the first and second switching circuits may be controlled as needed to maintain the sensed first and second voltages at desired values and/or ranges.
