MULTICHIP SEMICONDUCTOR STRUCTURE WITH INTEGRATED CIRCUIT AND ITS PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide a multichip semiconductor structure having an integrated circuit and a programmable circuit which protects the input-output nodes of chips from static discharge by providing the chips of a first semiconductor device and a second semiconductor chip electrically and mechanically coupled with each other in the multichip semiconductor structure. SOLUTION: A multichip semiconductor structure is provided with a first semiconductor chip having a first circuit which gives a prescribed circuit function and a second semiconductor chip which is electrically and mechanically coupled with the semiconductor chip. The second semiconductor chip has a second circuit which partially gives a circuit function to the first circuits. That is, a memory array chip 10 is provided wit memory arrays 12 which are divided from each other by a word decoder 14 for a word line having a tap at the center. The bit switch, sense amplifier, and driver 16 of the memory array 12 are arranged along the edge section 18 of the chip 10. The circuit 14 and driver 16 are called 'memory access circuits'.
