- STMicroelectronics (STM, Financial) introduces a groundbreaking memory solution for automotive microcontrollers.
- xMemory technology addresses growing automotive software complexity with double the memory density.
- The production of xMemory embedded in Stellar P6 MCUs is set to begin in late 2025.
STMicroelectronics (STM) has announced the launch of Stellar with xMemory, an innovative memory solution aimed at simplifying the development of software-defined vehicles (SDV) and electric vehicle platforms. This new technology is embedded into STM's Stellar series of automotive microcontrollers, targeting new drivetrain trends and electric vehicle architectures.
Utilizing proprietary phase-change memory (PCM), the xMemory solution addresses the increasing memory demands driven by artificial intelligence applications, over-the-air updates, and complex automotive software systems. It boasts the industry's smallest embedded non-volatile memory cell size, with PCM fabricated at 18nm and 28nm nodes, offering twice the memory density compared to other technologies like RRAM, MRAM, and Flash.
The new memory architecture allows carmakers to future-proof their designs with a single device rather than managing multiple memory options, thereby reducing development costs and expediting time-to-market. This scalable platform simplifies the supply chain and allows for post-launch memory upgrades through over-the-air updates. STM's xMemory is a strategic advancement in automotive semiconductor technology, poised to enter production on Stellar P6 MCUs in late 2025.
