Abstract:
1. A multi-chip module, comprising: a first integrated circuit (IC) die; a second IC die, in a stacked arrangement relative to the first IC die, having an input/output (I/O) node configured to electrically couple to the first IC die by a through substrate via (TSV) in the second IC die; and a fuse on an active surface of the second IC die that is configured to electrically couple to the I/O node, wherein the fuse is configured to allow an electrostatic discharge (ESD) current surge to go directly to ground and bypass an amplifier circuit of the second die to protect the amplifier circuit from damage caused by the ESD current surge, and the amplifier circuit is configured to generate a fuse-blow current to transition the fuse from a closed state to an open state to electrically disconnect the I/O node from ground and provide output signals and/or receive input signals at the I/O node.
