Abstract
A chip and a chip test system are provided by the present invention. The chip includes a decoding module and a test mode control module, and decodes an input signal to determine whether the input signal is a pre-activation signal or not. If the input signal is decoded into a pre-activation signal, then the chip will respond to a subsequent test signal; otherwise, the chip will not respond to any subsequent test signal. According to the present invention, by configuring a pre-activation signal, the number of chips to be simultaneously connected to and individually tested by the test equipment can be increased, without the need to occupy more input/output (I/O) interfaces.
