Advanced packaging (3D and chiplets)

Which correctly describes SiP (system in package)?

  1. ASeveral chips and passive components are housed in one package to function as a system
  2. BAll functions are integrated on one chip
  3. CA system is built with software alone
Show answer and explanation

Answer: A. Several chips and passive components are housed in one package to function as a system

SiP builds a processor, memory, passive components and so on into one package to function as one system. Compared with an SoC, which integrates everything on one chip, it makes it easier to combine parts from different processes and can shorten development time.
