Rambus has expanded its portfolio of interface and security digital IP with a memory controller designed for artificial intelligence 2.0 (AI 2.0).
Called GDDR7, the memory controller provides bandwidth-efficient solutions for GDDR7 memory with support for 40 Gbps operation providing 160 GB/s throughput. Rambus said this is an increase of 67% over the highest GDDR6 controller.
The controller could be used to design new GDDR7 memory deployments for AI accelerators, graphics and high-performance computing (HPC) applications.
Other features of the device include:
- PAM3 and NRZ signaling support
- Range of GDDR7 device sizes and speeds
- Low latency
- Flexible AXI interface support
- Low power support
- Reliability, availability and serviceability (RAS) features
- Comprehensive memory test support
- Integration support for third-party PHYs available
- Validated utilizing the latest GDDR7 VIP and memory vendor memory models
Rambus said AI 2.0 will allow for growth in large language models (LLMS) and the ability to create new multimodal content — text, images, speech, music, video that can be combined as inputs to create outputs in all these media. This could include creating a 3D model from an image or a video via text prompt.
