Synopsys HBM4 Controller IP

The Synopsys HBM4 Controller IP is optimized for power, latency, bandwidth, and area, supporting the JEDEC HBM4 standard. It interoperates with Synopsys HBM4 PHY IP through an extended DFI interface, delivering a complete memory interface solution. With pseudo channel support and flexible configuration options, the controller enhances memory bandwidth. Software configuration registers are accessible via the Arm AMBA APB specification interface. Key features include an advanced dynamic memory access command scheduler (e.g., CAM), Quality of Service (QoS) classes, a memory protocol handler (such as refresh and refresh management), power-saving capabilities (self-refresh, power down, DFI low power, frequency change), reliability and serviceability (RAS) features (Read/Write DQ parity, command access parity, SEC-DED ECC), PHY management, DRAM maintenance control (controller update, PHY update, controller message), and dual pseudo-channel support.
