Data reception chip

摘要

A data reception chip coupled to an external memory including a first input-output pin to output first data and including a comparison module and a voltage generation module is provided. The comparison module is coupled to the first input-output pin to receive the first data and compares the first data with a first reference voltage to identify the value of the first data. The voltage generation module is configured to generate the first reference voltage and includes a first resistor, a second resistor, a first capacitor and a second capacitor. The second resistor is serially connected to the first resistor. The first and second resistors divide a first operation voltage to generate the first reference voltage. The second capacitor is serially connected to the first capacitor. The first and second capacitors direct the first reference voltage to track the noise of the first operation voltage.
