Memory IP Solutions

Our family of memory PHYs offers a number of compelling benefits to chip and system designers alike, including reduced power consumption, increased data rates and improved cost-effectiveness – giving designers the advantage of increased margin and flexibility. These solutions are applicable to a broad range of applications spanning from mobile, to consumer to enterprise.

Rambus PHYs incorporate innovations such as FlexPhase™ timing adjustment circuitsoutput driver and On Die Termination (ODT) calibration that allow system designers to optimize for their unique requirements.

R+ DDRn PHY Configuration image

As part of a complete solution, our PHYs contain all of the necessary components for robust operation and ease of integration. They consist of hard macros of the command/address (C/A) and 8-bit data cells, and include IO pads, phase lock loops (PLL), power mode management (PMM), transmit and receive paths, clock distribution, control logic, power distribution and electrostatic discharge (ESD) protection circuitry. Outside of the PHY itself, our solutions also include complete documentation and access to our in-house experts for optional design integration and bring-up support services to make integration as straightforward as possible.

Going Beyond GPUs with GDDR6

Going Beyond GPUs with GDDR6

Supported by Micron Technology, SK Hynix and Samsung, GDDR6 SGRAM will feature a maximum data transfer rate of 16 Gbps, along with an operating voltage of 1.35V. GDDR6 offers higher densities compared to previous-generation graphics memory. In addition, GDDR6 doubles the speed (12–16 Gb/s) of GDDR5 and provides more than 5X the 3.2 Gb/s speed of DDR4. Although initially targeted at game consoles and PC graphics, the latest iteration of GDDR is expected to be deployed across multiple verticals, with Micron specifically highlighting the data center and automotive sector.
