Rambus unveils Mobile XDR memory architecture

LOS ALTOS, USA: Rambus Incorporated, one of the leading technology licensing companies in the world, has unveiled its Mobile XDR memory architecture for next-generation mobile products.

The Mobile XDR memory – based on innovations from the innovative Mobile Memory Initiative that Rambus introduced in 2009 – offers a high-bandwidth, low-power memory architecture to enable devices which exceed the power and performance targets for next-generation mobile products, according to Sharon Holt, senior vice-president (licensing and marketing) of Rambus.

Sharon Holt said the Mobile XDR memory gives designers the ideal solution to offer leading-edge mobile content in a “dramatically lower power and cost-effective way.” The Mobile XDR architecture delivers these benefits, Sharon Holt added, in SoC and DRAM devices, which can be built with existing manufacturing infrastructure – thus cutting both risk and time-to-market.

The Mobile XDR memory architecture, Rambus claims, will enable future mobile memory platforms that can achieve throughputs of up to 4.3Gbps per pin with “unequaled” power efficiency. With this novel performance, SoC platforms can attain over 17GB/s of memory bandwidth from a single Mobile XDR DRAM device, even while extending the battery life of many mobile products by over 30 minutes, when operating under the “most power-hungry” usage profiles.

According to Rambus, the key components of the Mobile XDR memory architecture are the Mobile XDR DRAM, the Mobile XDR memory controller (MXC), and the Mobile XDR memory controller PHY (MIO).
