Providing a Complete Solution for HBM4

The Cadence High-Bandwidth Memory generation 4 (HBM4E) PHY is optimized for systems that require the highest-bandwidth, low-latency memory solution. The memory subsystem consisting of PHY and controller supports data rates up to 12.8Gbps per data pin, featuring 32 independent channels, for a total data width of 2048 bits. The PHY is designed for a 2.5D system with a silicon interposer to route signals between the 3D DRAM stack and PHY.
