DFI 3.1 specification released; Supports LPDDR3 memory for smartphones and tablets

The DDR PHY Interface (DFI) Group has released the DFI 3.1 specification, the latest version of the pervasive industry specification that defines an interface protocol between DDR memory controllers and PHYs. The specification enables the development of systems-on-chip (SoCs) that support the DDR3 and DDR4 memory standards. Version 3.1 adds support for the LPDDR3 mobile memory standard for smartphones and tablets. The new version also supports enhancements to the low power interface and training features. The DFI interface standard was developed through the collaborative effort of leaders in the semiconductor and EDA markets and has become the de facto industry standard for high-bandwidth memory interfaces.

"Consumer mobile electronics continue to demand both increased memory performance and power efficiency, requiring the use of new technologies such as LPDDR3 memory," said John MacLaren, chairman of the DFI Group. "We are excited to add LPDDR3 mobile memory support to the DFI standard as it means the benefits of this technology will now be available to the rapidly growing mobile computing market."

The preliminary DFI 3.1 memory specification is available now for download at www.ddr-phy.org
