ACTIVE PACKAGE SUBSTRATE HAVING EMBEDDED INTERPOSER

Semiconductor packages including active package substrates are described. In an example, the active package substrate includes an active die and an interposer embedded within a substrate laminate. The active die may be mounted on the interposer, and die pads of the active die may be electrically connected to a first contact array of the interposer. Accordingly, signal routing of the interposer may fan out an electrical signal from the embedded die pads to several vias in the substrate laminate. One or more memory dies of a memory stack may be mounted on substrate laminate and may be electrically connected to the vias. Accordingly, the embedded active die may control the memory stack.
