I/O CELL ESD SYSTEM

摘要

An ESD protection system for I/O cells of an integrated circuit. The I/O cells of a bank of cells (201) include a first type of I/O cells (211) having ESD trigger circuits and a second type of I/O cells (213) having ESD clamp devices (241). In one embodiment, the ESD trigger circuits of the first type are located at the same area of an active circuitry floor plan as the area in the floor plan for the ESD clamp devices of the I/O cells of the second type.
