DDR Interface
Socionext provides various DDR interface macros from low-to-middle speed forwarding bandwidth to high-speed forwarding bandwidth or low power, with various process technologies. Moreover, we support custom SoC development by LSI-Package-Board co-design.
[DDR Interface macros]
• High-speed/ high-bandwidth : DDR3/DDR4
• Low Power : LPDDR4/LPDDR3/LPDDR2/DDR3L
• DFI compliant (all macro)
• Compatible with many different DRAM configurations and PKG options,
such as Fly-by and PoP thanks to the PHY function (training function).
• Low Power : LPDDR4/LPDDR3/LPDDR2/DDR3L
• DFI compliant (all macro)
• Compatible with many different DRAM configurations and PKG options,
such as Fly-by and PoP thanks to the PHY function (training function).
