Patent number: 6119253Abstract: A method for setting test modes in a semiconductor ship and a device suitable for the method are provided. In the method, a power voltage is externally applied to the semiconductor chip. A predetermined signal is applied to an arbitrary selected external pin of the semiconductor chip. A first-state signal is applied to the test pin and a second-state signal is applied to the test pin a predetermined time later. The signal applied to the external pin is latched by the first-state signal applied to the test pin. The second-state signal applied to the test pin, a predetermined signal output when the first-state signal applied to the test pin is shifted to the second-state signal, and the latched signal are logically combined and the combined signal is output.Type: GrantFiled: October 17, 1997Date of Patent: September 12, 2000Assignee: Samsung Electronics, Co., Ltd.Inventors: Won-kyum Kim, Kwang-jae Jung
