Abstract
A semiconductor apparatus includes a transmission device and a receiving device. The transmission device generates an output signal from a transmission signal in synchronization with a clock signal. The receiving device generates a reception signal from the output signal in synchronization with the clock signal and a delayed clock signal generated by delaying the clock signal by a preset time, based on an operating speed of the semiconductor apparatus.
Claims17
A semiconductor apparatus comprising:
- a transmission device configured to output a transmission signal as an output signal in synchronization with a clock signal, and output the output signal at one of a first time and a second time, the second time being earlier than the first time, based on an operation information signal;
- and
- a receiving device configured to receive the output signal and the clock signal and generate a reception signal by delaying the output signal by a time corresponding to one of a third time and a fourth time, the fourth time being later than the third time, based on the operation information signal.
A semiconductor apparatus comprising:
- a transmission device configured to generate an output signal from a transmission signal in synchronization with a clock signal;
- and
- a receiving device configured to receive the output signal and the clock signal, and generate a reception signal from the output signal in synchronization with the clock signal and a delayed clock signal which is generated by delaying the clock signal by a preset time.
A semiconductor apparatus comprising:
- a transmission device configured to transmit an output signal in correspondence to a clock signal, transmit the output signal at a first time when the semiconductor apparatus operates with a low frequency, and transmit the output signal at a second time, the second time being earlier than the first time, when the semiconductor apparatus operates with a high frequency, the high frequency being greater than the low frequency;
- and
- a receiving device configured to receive the clock signal and the output signal, generate a reception signal by synchronizing the output signal with the clock signal when the semiconductor apparatus operates with a low frequency, and generate the reception signal by synchronizing the output signal with a delayed clock signal generated, by delaying the clock signal by a preset time, when the semiconductor apparatus operates with a high frequency.
