Abstract: In an embodiment, a structure includes: a first integrated circuit die including first die connectors; a first dielectric layer on the first die connectors; first conductive vias extending through the first dielectric layer, the first conductive vias connected to a first subset of the first die connectors; a second integrated circuit die bonded to a second subset of the first die connectors with first reflowable connectors; a first encapsulant surrounding the second integrated circuit die and the first conductive vias, the first encapsulant and the first integrated circuit die being laterally coterminous; second conductive vias adjacent the first integrated circuit die; a second encapsulant surrounding the second conductive vias, the first encapsulant, and the first integrated circuit die; and a first redistribution structure including first redistribution lines, the first redistribution lines connected to the first conductive vias and the second conductive vias.

Abstract: The present disclosure provides a server system that comprises: a CPLD comprising a first firmware and a first serial peripheral interface; and a serial peripheral read-only memory comprising a second firmware and a second serial peripheral interface; wherein the first serial peripheral interface electrically connects to the second serial peripheral interface through a serial peripheral signal. The CPLD detects the first firmware and the second firmware when the server system is booting. The CPLD sets the first firmware as a main firmware and the first firmware is used for a booting of the server system when the first firmware is detected. The CPLD sets the second firmware as the main firmware when the first firmware is not detected and the second firmware is detected. Through the technical solution of the present disclosure, the server can ensure the normal operation of the system even the CPLD firmware has a problem.
