First test system for LPDDR6

Keysight has developed the first test system for the next generation Low-Power Double Data Rate 6 (LPDDR6) memory technology.

The LPDDR6 test automation system is based on Keysight’s UXR oscilloscope and high-performance M8040A Bit Error Ratio Tester. This can significantly improve device and system validation, providing new test automation tools necessary for AI system development, especially in mobile and edge devices.

LPDDR6 significantly enhances performance and efficiency to support next-generation compute system requirements, making it a crucial upgrade for contemporary devices.

Test complexity has grown with the adoption of next-generation memory devices such as LPDDR6, HBM4, and GDDR7. These technologies demand advanced test methods to ensure reliability and performance while reducing test times and maintaining accuracy.

The workflow consists of transmitter and receiver test applications and the Advanced Design System (ADS) Memory Designer workflow solution. The LPDDR6 test solution can be paired with Keysight’s EDA software and the Memory Designer bundle from simulation to verification and test.

The new memory standard’s combination of high performance and power efficiency makes it particularly suitable for AI and machine learning applications, high-speed digital computing, automotive systems, data centres, and other edge applications areas where the balance between processing power and energy consumption is crucial.

The test system can be used to validate designs confidently using proven Bit Error Ratio testing methodology and pinpoint performance issues early by testing against multiple jitter, crosstalk, and noise scenarios. This can maximize signal integrity through detailed BER analysis and receiver equalization optimization.

“As a leader in memory design and test solutions, Keysight continues to collaborate with JEDEC to develop the LPDDR6 standard. This new LPDDR6 standard is set to revolutionize the market, offering unprecedented speed, efficiency, and reliability, enabling the industry’s AI Edge rollout. As the deployment and use of next-generation memory devices are growing, Keysight has achieved a significant milestone in enabling faster time to market for LPDDR6 memory designs,” said Dr. Joachim Peerlings, Vice President and General Manager, Network and Datacenter Solutions.

The new receiver and transmitter system will be shown to the public for the first time at DesignCon 2025 from tomorrow.
