Abstract
A data I/O interface for an integrated circuit device includes a noise detector receiving a power supply voltage, detecting a power supply voltage noise component, and providing a clock delay control signal in response to detected power supply voltage noise component. The data I/O interface also includes a clock delay circuit providing a delayed clock signal in response to the clock delay control signal, and a data transfer circuit powered by the power supply voltage and providing output data synchronously with the delayed clock signal.
