    摘要: A multiple integrated circuit chip structure provides interchip communication between integrated circuit chips of the structure with no ESD protection circuits and no input/output circuitry. The interchip communication is between internal circuits of the integrated circuit chips. The multiple integrated circuit chip structure has an interchip interface circuit to selectively connect internal circuits of the integrated circuits to test interface circuits having ESD protection circuits and input/output circuitry designed to communicate with external test systems during test and burn-in procedures. The multiple interconnected integrated circuit chip structure has a first integrated circuit chip mounted to one or more second integrated circuit chips to physically and electrically connect the integrated circuit chips to one another. The first integrated circuit chips have interchip interface circuits connected each other to selectively communicate between internal circuits of the each other integrated circuit chips or test interface circuits, connected to the internal circuits of each integrated circuit chip to provide stimulus and response to said internal circuits during testing procedures. A mode selector receives a signal external to the chip to determine whether the communication is to be with one of the other connected integrated circuit chips or in single chip mode, such as with the test interface circuits. ESD protection is added to the mode selector circuitry.
