    Abstract: There are provided a data buffer and a memory system having the same. The data buffer includes first and second amplifiers configured to output output data by inverting input data, the first and second amplifiers having coupled output nodes to which the output data is output, wherein both of the first and second amplifiers are activated to output the output data when the input data has a first swing level, and wherein one of the first and second amplifiers is activated to output the output data when the input data has a second swing level narrower than the first swing level.

    Abstract: A voltage generation circuit may include: a first transistor coupled to an internal supply voltage terminal, and configured as a diode-connected transistor; a second transistor coupled to the first transistor and configured as a diode-connected transistor; and a third transistor coupled between the second transistor and a ground voltage terminal, and configured to operate according to a first reference voltage generated based on an external supply voltage. The voltage generation circuit may limit a variation in level of a second reference voltage which is generated through a drain terminal of the second transistor as a threshold voltage of the second transistor rises according to a rise in level of the internal supply voltage.

    Abstract: A signal receiving device may include a high-speed receiving circuit, a low-speed receiving circuit, a low-speed synchronization circuit and a low-speed synchronization circuit. The high-speed receiving circuit receives an input signal and generate a high-speed received signal in a first operation mode. The high-speed synchronization circuit generates a high-speed synchronized signal to synchronize the high-speed received signal with a clock signal. The low-speed receiving circuit receives the input signal and generate a low-speed received signal in a second operation mode. The low-speed synchronization circuit generates a low-speed synchronized signal to synchronize the low-speed received signal with the clock signal. According to an operation mode, one of the high-speed synchronized signal and the low-speed synchronized signal is selected as an internal signal.
