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 development for signal quality and cost optimization through design support by Chip-Package-Board co-design.

●DDR Interface macros
- High-speed/ high-bandwidth : DDR3/DDR4
- Low Power : LPDDR4X/4/3/2DDR3L
- DFI compliant (all macro)
- Compatible with many different DRAM configurations and PKG options, such as Fly-by, PoP, and DIMM thanks to the PHY function (training function).
●DDR interface design support (Chip–Package–Board codesign)
- Timing verification : Verifies the timing of all DDR-IF systems including delays between LSI I/O and DRAM
- Power Integrity : Optimizes the parasitic inductance, resonant frequency, and power supply (PKG, PCB) impedance as part of the power supply impedance design
- Signal Integrity : Optimizes Driver strength, terminator resistance, and interconnect topology

PCI Express Interface
As a result of the recent rapid improvement in CPU processing capability and an increase in the need for high capacity data transfer, it has become extremely difficult to achieve the expected system performance with existing buses. The PCI Express technology is a high-speed interface capable of transferring several hundred megabytes of data that can overcome this issue.
Socionext’s PCI Express macro supports up to 8GT/s (Gen3) and passed the PCI Express standard compliance test hosted by the Peripheral Component Interconnect Special Interest Group (PCI-SIG), and its interconnectivity and reliability have been confirmed with many PCI Express interfaces.
