Overview

The Cadence® Denali® HBM2E/2 PHY and Controller IP is silicon-proven and includes architectural improvements drawn from previous-generation DDR5 and LPDDR4 PHYs, achieving breakthrough performance, low energy per bit, and low area relative to the data bandwidth. It is engineered to quickly and easily integrate into SoCs and is verified as part of a complete memory subsystem solution. The HBM2E/2 PHY and Controller IP is an ideal solution for artificial intelligence (AI), high-performance computing (HPC), and image processing applications.
