# Spin Memory

> Spin Memory, formerly Spin Transfer Technologies, was a Fremont semiconductor company developing magnetic memory devices and licensable MRAM technology. Its partners included Arm, Applied Materials and Tokyo Electron. The board decided to liquidate in June 2021 after customer-acquisition difficulties, delayed testing and funding constraints.

- **Founded:** 2007
- **Headquarters:** Fremont, United States
- **Founders:** Andrew D. Kent (Scientific founder; NYU physics professor)
- **Products:** OST-MRAM / ST-MRAM evaluation devices, Endurance Engine, Precessional Spin Current / Spin Polarizer, Universal Selector, MRAM process IP
- **Notable:** Delivered functional customer samples in 2017., Signed Arm and Applied Materials commercial agreements in 2018., Announced Universal Selector in August 2020.

## Products & services
