HBM3/2E/2 IP Subsystem

The HBM3/2E/2 IP is ideal for applications involving graphics, high-performance computing, high-end networking, and communications that require very high bandwidth, lower latency, and more memory density.


Integrated HBM controller and HBM PHY subsystem solution that supports HBM3, HBM2E, and HBM2 JEDEC specifications for a wide range of technology and foundry nodes. As an early advocate of 2.5D and 3D ASIC design technologies and by leveraging its experience from the industry’s first multiple successful 2.5D SOC System in Package (SiP) demonstrations, Alphawave Semi plays a key role in enabling industry applications that leverage HBM 3D-stacked DRAM technology.
