ABSTRACT:
An electrostatic discharge protection system for an integrated circuit device, such as a solid state memory device or any other integrated circuit device having a plurality of individual power groups, includes a loop of an electrically conductive material that is disposed on the device defining a electrostatic discharge path portion, a plurality of first punch-through devices which connect the input/output pins of different power groups of the integrated circuit device to the power sources of the associated power group, and a plurality of second punch-through devices which connect all of the input/output pins of the integrated circuit device to the electrostatic discharge path portion, thereby providing a discharge path that is common to all of the power groups of the integrated circuit device.
