GDDR6 Controller

Overview

High-performance IP for graphics, AI/ML, and automotive products

The silicon-proven GDDR6 PHY and controller IP showcase leading-edge BER, BIST, and RAS capabilities. GDDR6 offers significantly more performance than the fastest speed of DDR5 at a moderate cost, making it ideal for high-bandwidth applications. Cadence’s unique, single-vendor GDDR6 IP solution speeds up integration and reduces interoperability risk.

Key Features

  • In-line SEC/DED ECC
  • Supports advanced RAS features including error scrubbing, parity, etc.
  • Compatible with GDDR6 devices compliant to JESD250b
  • Single and multi-port host options for Arm® AMBA®4, AMBA 3 AXI, and low-latency Denali interfaces
  • QoS features allow command prioritization
  • Flexible paging policy
  • Memory controller interface is based on DFI 5.0
  • The controller runs at 1/8 of the memory clock speed for ease of timing closure

Benefits

  • Proven: Silicon characterization reports available in multiple process technologies and foundries
  • Low Latency: For data-intensive applications
  • Low Power and Area: Industry-leading PPA based on advanced architecture and implementation
  • Low BER: Supporting standard PCB materials
  • Reliable: Maximum system margin with advanced clocking and I/O architectures
  • Future proof: Cutting edge technology with the latest GDDR protocols and the highest data rates
