DES Key Search
https://www.rambus.com/des-key-search/Record Breaking DES Key Search Completed A machine built by Cryptography Research, Advanced Wireless Technologies, and EFF has demonstrated fast key search for the Data Encryption Standard (DES). DES, the most widely used commercial encryption algorithm, protects financial transactions and electronic communications worldwide. Developed by the US Government and IBM in the 1970s, DES is […]
VirtuOptic™ Reflectors
https://www.rambus.com/virtuoptic-reflectors/VirtuOptic™ reflectors deliver a highly efficient, collimated light pattern that can be evenly distributed over wide areas, making it ideal for high brightness architectural, entertainment and commercial lighting applications. When combined with Rambus’ proprietary optical modeling and design techniques, the shape and size of the VirtuOptic reflectors can be optimized to achieve a highly-controlled, directed […]
Very Low-Swing Differential Signaling
https://www.rambus.com/very-low-swing-differential-signaling/Today’s mobile device demand high bandwidth for HD video capture and streaming, and media-rich web browsing as well as extended battery life. Very Low-Swing Differential Signaling (VLSD) is a bi-directional, ground-referenced, differential signaling technology which offers a high-performance, low-power, and cost-effective solution for applications requiring extraordinary bandwidth and superior power efficiency. Enables high data rates […]
TruEdge™ LED Coupling
https://www.rambus.com/truedge-led-coupling/The growing popularity of LEDs in general lighting applications has introduced great opportunities for a new generations of energy-efficient lighting, but LEDs are not without their difficulties. Designers are challenged with how to transform single, or multiple point sources of light into an aesthetically-pleasing, uniform distribution of light. The use of edge-lit architectures—where LEDs are […]
SolidCore™ Reflectors
https://www.rambus.com/solidcore-reflectors/Fixtures that use traditional free-space reflectors — those that allow light to travel through air — can be cumbersome and inefficient when producing high-intensity beams of light. As an alternative to free-space reflectors, SolidCore™ reflectors are compact optics that produce high-brightness, collimated beams ideal for high-powered spotlights. SolidCore™ Reflectors enable smaller, thinner and lighter-weight fixtures […]
On Die Termination Calibration
https://www.rambus.com/on-die-termination-calibration/As the performance requirements of digital systems continue to increase, there are increasing requirements to deliver signal integrity that enables reliable operation at higher signaling rates. Signal line terminations are useful elements in the management of signal integrity, and can be use external to the memory device or within the device itself. Incorporating a resistive […]
MicroLens® Optics
https://www.rambus.com/microlens-optics/The introduction of LEDs to the application of general lighting presents lighting architects and fixture designers with unprecedented capabilities unachievable with the constraints of bulb and fluorescent tube-based luminaires. In addition to lower cost, lower energy consumption, and greater control and directionality of light, LEDs offer tremendous freedom of design. However, as point sources of […]
Micro-Threading Technology
https://www.rambus.com/micro-threading-technology/Improvements in DRAM interface throughput have rapidly outpaced comparable improvements in core speeds. Whereas data rates of DRAM interfaces have increased by over an order of magnitude over successive generations, the DRAM core frequency has remained relatively constant. Over time, core prefetch size has increased in order to keep pace with improvements in interface bandwidth. […]
Fully Differential Memory Architecture
https://www.rambus.com/fully-differential-memory-architecture/As data rates continue to increase, signal and power integrity are increasingly difficult to maintain in memory systems with single-ended signaling topologies. To enhance signal integrity and noise immunity across all communications between the memory PHY and the DRAM devices, Rambus implemented a Fully Differential Memory Architecture (FDMA) using a point-to-point topology, for data, clock, […]
Fly-by Command Address
https://www.rambus.com/fly-by-command-address/Conventional, low-speed DRAM systems distribute clock, command, and address signals to multiple DRAMs using a topology in which those signals propagate to all of the DRAMs in the system at approximately the same time. In such systems, the propagation delays on the command and address lines introduce timing skew into the system, thereby limiting the […]
