Abstract
A parallel test circuit for a semiconductor memory device includes multiple data input pads, multiple data input buffers respectively connected to the data input pads for receiving write data in response to a chip selection signal during normal operation, and a switching circuit for electrically connecting the data input pads to each other in response to a current leakage test signal applied to the circuit. The circuit enables the detection of leakage current in the input data buffers at the same time that a parallel data writing test is performed, thereby reducing the total time required to test the device.
