Rambus unfolds DRAM innovations
beyond DDR3
Rambus has released new techniques in improving DRAM speed,
power consumption and performance to take them beyond current
DDR3 data rate limits of 3200Mbps.
The Rambus DRAM advancements include:
1. FlexPhase Technology - introduced in the XDR memory architecture,
can enable higher data rates compared
to direct strobing technology used in DDR3
2. Near Ground Signaling - supports high performance at
reduced IO power, allowing operation at 0.5V while
signal integrity
3. FlexClocking Architecture - introduced in Rambus' Mobile
Memory Initiative, reduces clocking power by
eliminating the need for a DLL or PLL on the DRAM
4. Module Threading - increases memory efficiency and reduces
DRAM core power, and when combined
with Near Ground Signaling and FlexClocking technology,
can cut total memory system power
by over 40%;
5. Dynamic Point-to-Point (DPP) - provides a path for capacity
upgrades through reliable point-to-point signaling.
Rambus has published a white paper providing more details
on these technologies. The whitepaper named "Challenges
and Solutions for Future Main Memory" is available
for download at www.rambus.com.
"Product advancements in multi-core computing, virtualization
and chip integration put ever-increasing demands on the
memory sub-system, a key performance limiter in today's
performance computing systems," said Craig Hampel,
Rambus Fellow. "This collection of breakthrough innovations
from Rambus allows for memory systems that are better suited
for the bandwidth and workloads of these throughput-oriented
multi-core processors, increasing the design and solution
space for future main memory to enable a new generation
of computing platforms."
