Abstract
A device is provided and includes a sense amplifier and an output latch circuit. The sense amplifier adjusts voltage levels of first and second data lines according to a bypass data signal corresponding to a data signal in response to a first enable signal having a first logic state and a second enable signal having a second logic state different from the first logic state during a test mode. The output latch circuit generates a data output signal according to the voltage level of the first data line in response to the first enable signal having the second logic state and a third enable signal having the first logic state during the test mode.
