What happened
Tohoku University and Aisin have developed an AI chip featuring embedded STT-MRAM that eliminates external DRAM and SSDs through near-memory computing. The architecture accelerates OS boot times by roughly 39 times, cuts object detection inference time to one-tenth, and reduces energy consumption to one-fiftieth compared to conventional designs. Manufactured on TSMC’s 16nm FinFET process, the SoC integrates a 32MB STT-MRAM array, an AI accelerator, two Arm Cortex-A53 CPU cores, and an Arm Mali-G31 GPU.
Key details
- Tohoku University and Aisin jointly developed a near-memory computing AI chip featuring embedded STT-MRAM on November 2, 2026.
- The chip is manufactured using TSMC’s 16nm FinFET process and integrates a 32MB STT-MRAM block, an AI accelerator, two Arm Cortex-A53 cores, and an Arm Mali-G31 GPU.
- The design reduces power-on to OS boot time by approximately 39 times, cuts object detection time to about one-tenth, and lowers energy consumption by a factor of 50.
What remains unclear
- Volume production schedule and target vehicle models for initial deployment
- Wafer pricing and yield economics of integrating STT-MRAM into a 16nm FinFET baseline process
- Plans for commercial licensing beyond Aisin’s proprietary automotive applications

Japanese industrial firms are aggressively pursuing edge-AI architectures that bypass memory bandwidth bottlenecks without relying on power-hungry external DRAM. This development underscores how traditional automotive suppliers like Aisin are vertically integrating specialized silicon to meet the rigorous latency and thermal constraints of software-defined vehicles.
