Abstract
Abstract An electronic package which has a plurality of stacked integrated circuit dies. The package includes a first die that is mounted to a die paddle of a lead frame. The first die is also connected to the leads of the lead frame by bond wires. A second die is mounted to the top surface of the first die and electrically connected to the first die with bond wires. The first die, second die and die paddle are all enclosed by a package.
