Abstract: Multichip semiconductor structures with consolidated circuitry are disclosed, along with programmable electrostatic discharge (ESD) protection circuits for chip input/output (I/O) nodes. The multichip structures include a first semiconductor chip having a first circuit at least partially providing a first predetermined circuit function, and a second semiconductor chip electrically and mechanically coupled to the first semiconductor chip. The second semiconductor device chip has a second circuit that at least partially provides a circuit function to the first circuit of the first semiconductor chip. In one embodiment, the first semiconductor chip includes a memory array chip, while the second semiconductor chip includes a logic chip wherein at least some peripheral circuitry necessary for accessing the memory array of the memory array chip resides within the logic chip. This allows the removal of redundant circuitry from identical chips of a multichip structure.
