A controller includes an input/output circuit and a reference voltage generating circuit. The input/output circuit includes a plurality of receiving circuits. Each receiving circuit receives and processes one data bit and generates an output bit accordingly. The reference voltage generating circuit is coupled to the input/output circuit and includes a plurality of circuit units for providing a plurality of reference voltages. One of the circuit units is coupled to one of the receiving circuits to provide a reference voltage to the corresponding receiving circuit and the receiving circuit processes the data bit according to the received reference voltage.

Methods for generating reference voltages and controllers utilizing the same

A data reception chip coupled to an external memory including a first input-output pin configured 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 to compare 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. The voltage generation module includes a first resistor and a second resistor. The second resistor is connected to the first resistor in series. The first and second resistors divide a first operation voltage to generate the first reference voltage.
