M31 Expands Rambus Collaboration, Strengthening Its One-Stop MIPI Subsystem Solution

This collaboration combines these controller capabilities with M31’s silicon-proven MIPI PHY portfolio with a strong track record of successful deployments, enabling M31 to offer a comprehensive MIPI subsystem solution integrating high-speed MIPI PHYs and MIPI CSI/DSI controllers to address the growing requirements of high-resolution imaging and display applications.

M31 High-Speed and Long-Channel MIPI C/D-PHY Solution on TSMC N3P/N3C

With the rapid growth of AR/VR and high-resolution imaging systems such as drones and action cameras, MIPI CSI (Camera Serial Interface) and MIPI DSI (Display Serial Interface) require both high data throughput and low power consumption. M31 provides a MIPI C-PHY and D-PHY IP combo solution implemented on TSMC N3P and N3C processes.

M31 Gains Momentum in Advanced Processes, Targets Double-Digit Growth in 2026

Consolidated revenue for the first quarter reached NT$395 million, representing a year-over-year decrease of 9.2%. The decline was primarily attributable to timing fluctuations in contract signings for certain key advanced-node customers in North America, with the related revenue expected to be recognized in the second quarter.
