Abstract
Embodiments of the present invention generally provide techniques and apparatus for altering the functionality of a multi-chip package (MCP) without requiring entire replacement of the MCP. The MCP may be designed with a top package substrate designed to interface with an add-on package that, when sensed by the MCP, alters the functionality of the MCP.
