Abstract
A data reading device and a data reading method for design-for-testing are provided. The data reading device includes a buffer and a data serialization circuit. The data serialization circuit receives a clock positive edge-triggered signal, a clock negative edge-triggered signal, a trigger mask signal, and test data. The data serialization circuit masks one of the clock positive edge-triggered signal and the clock negative edge-triggered signal according to the trigger mask signal, and provides a part of the test data to an output terminal of the data serialization circuit as an output signal of the data reading device according to the unmasked one of the clock positive edge-triggered signal and the clock negative edge-triggered signal. Thus, a data valid window of the test data can be increased.
