    摘要: An on-die termination (ODT) circuit may include an ODT synchronous buffer and/or an ODT gate. The ODT synchronous buffer may be configured to generate a synchronous ODT command from an external ODT command in synchronization with a first clock signal delay-locked to an external clock signal. The ODT gate may be configured to generate signals for controlling ODT based on a second clock signal delay-locked to the external clock signal and the synchronous ODT command. The synchronous ODT command may be generated in a disabled period of the second clock signal.

    摘要: A buffer has an amplifier that receives an external signal, a reference voltage, and outputs an amplified signal. The amplified signal is responsive to the difference between the external signal and the reference voltage. An inverter receives the amplified signal and generates an inverted signal. A voltage supply circuit is configured to provide an adjusted power supply voltage to the inverter responsive to the reference voltage. A ground voltage supply circuit is configured to provide an adjusted ground voltage to the inverter responsive to the reference voltage.
