Rambus targets 17Gbyte/s bandwidths
Rambus has launched what it calls its Mobile Memory Initiative, which focuses on developing high bandwidth, low power memory technologies. According to the company, it is looking to enable data rates of 4.3Gbit/s, which would enable a memory bandwidth of more than 17Gbyte/s from one mobile dram.
“As consumer expectations grow for more media rich applications on their mobile devices,” said Martin Scott, Rambus’ senior vice president of Research and Technology Development, “new memory solutions will be needed to keep pace. With the technologies developed through the Mobile Memory Initiative, Rambus enables a broad range of advanced mobile applications.”
Key innovations are said to include: very low swing differential signalling; the FlexClocking architecture; and advanced power state management.
Very low swing differential signalling combines the robust signalling of differential architectures with innovative circuit techniques to reduce active power consumption. The FlexClocking architecture is a clock forwarded and clock distributed topology, enabling high speed operation and a simplified dram interface, while advanced power state management – in conjunction with the FlexClocking architecture – provides fast switching between power saving modes and optimised power efficiency.
