Characteristics of System in a Package of Synchronous Dynamic Random Access Memory for High-Speed Data Storage Applications

This paper proposes a system in a package (SiP) integrating a system on a chip (SoC) and a double-data-rate-three synchronous dynamic random access memory (DDR3 SDRAM) for advanced data-storage-based systems. The characteristics of high frequency, signal integrity (SI), and power integrity (PI) were investigated for the SoC/DDR3-SDRAM SiP. The SiP exhibited low insertion loss, wide eye-diagram aperture, and low power impedance. The effect of de-coupling capacitors on the SiP was also examined. The SoC/DDR3-SDRAM SiP achieved excellent performance for high-speed data storage applications.
