Rambus Introduces a Memory Subsystem Capable of 8.4 Gbps HBM3

Rambus announced the Rambus HBM3-ready memory interface subsystem consisting of a fully-integrated PHY and digital controller.

Supporting breakthrough data rates of up to 8.4 Gbps, the solution can deliver over a terabyte per second of bandwidth, more than double that of high-end HBM2E memory subsystems. With a market-leading position in HBM2/2E memory interface deployments, Rambus is ideally suited to enable customers' implementations of accelerators using next-generation HBM3 memory.

"The memory bandwidth requirements of AI/ML training are insatiable with leading-edge training models now surpassing billions of parameters," said Soo Kyoum Kim, associate vice president, Memory Semiconductors at IDC. "The Rambus HBM3-ready memory subsystem raises the bar for performance enabling state-of-the-art AI/ML and HPC applications."Benefits of the Rambus HBM3-ready Memory Interface Subsystem:

• Supports up to 8.4 Gbps data rate delivering bandwidth of 1.075 Terabytes per second (TB/s)
• Reduces ASIC design complexity and speeds time to market with fully-integrated PHY and digital controller
• Delivers full bandwidth performance across all data traffic scenarios
• Supports HBM3 RAS features
• Includes built-in hardware-level performance activity monitor
• Provides access to Rambus system and SI/PI experts helping ASIC designers to ensure maximum signal and power integrity for devices and systems
• Includes 2.5D package and interposer reference design as part of IP license
• Features LabStation development environment that enables quick system bring-up, characterization and debug
• Enables the highest performance in applications including state-of-the-art AI/ML training and high-performance computing (HPC) systems

Rambus achieves HBM3 operation of up to 8.4 Gbps leveraging over 30 years of high-speed signaling expertise, and a strong history of 2.5D memory system architecture design and enablement. In addition to the fully-integrated HBM3-ready memory subsystem, Rambus provides its customers with interposer and package reference designs to speed their products to market.

"With the performance achieved by our HBM3-ready memory subsystem, designers can deliver the bandwidth needed by the most demanding designs," said Matt Jones, general manager of Interface IP at Rambus. "Our fully-integrated PHY and digital controller solution builds on our broad installed base of HBM2 customer deployments and is backed by a full suite of support services to ensure first-time right implementations for mission-critical AI/ML designs."
