The MNEMOSYNE Radiation-Hardened Memory Family from 3D PLUS is officially qualified and in series production
The MNEMOSYNE project, led by 3D PLUS and funded by the European Union under the Horizon 2020 programme, was launched in 2019 with the aim of developing a new generation of radiation-hardened, high-density, non-volatile memory for space applications. Another goal was to ensure a long-term supply and to guarantee that production would take place entirely in Europe, thereby achieving independence from other countries. The name ‘MNEMOSYNE’ was inspired by the Greek goddess of the same name, who is considered the personification of memory.
Led by the 3D PLUS team, this project brought together leading experts in radiation effects and space electronics from institutions such as IMEC, the University of Padua, TRAD, NanoXplore and Beyond Gravity, who worked together on the MNEMOSYNE project. Following the successful development and qualification of the ASIC, full production of the entire MNEMOSYNE memory product line has commenced. The product line is ready for integration into space systems and offers an innovative storage solution that sets new standards in the space industry.
What is MNEMOSYNE
MNEMOSYNE is a state-of-the-art, radiation-insensitive, non-volatile memory (NVM) solution based on 22nm STT-MRAM FDSOI technology, tailored to meet the exacting demands of space applications. MNEMOSYNE modules integrate stacked, radiation-insensitive memory ASICs to achieve industry-leading density. These provide excellent data retention and extreme write endurance. The modules are available with serial or parallel interfaces and are supplied in SOP housings that enable robust SMT mounting and ensure resilience in harsh thermal and mechanical environments.
MNEMOSYNE memories are specifically designed for extreme space conditions and offer a total ionising dose of over 100 krad (Si), as well as high immunity to single-event effects. Thanks to its unrivalled reliability and density, MNEMOSYNE is the ideal solution for configuring the latest SRAM-based field-programmable gate arrays (FPGAs). It also serves as secure boot and programme memory for next-generation processors, as well as providing a reliable solution in highly radiated space environments.
Qualification, availability and the MNEMOSYNE product families
According to 3D PLUS, after six years since the start of the MNEMOSYNE project, all MNEMOSYNE memories are now fully qualified and ready for series production, with samples available immediately. The company used its advanced 3D stacking technology to develop three product lines based on the SEE-immune MNEMOSYNE ASIC. Each module combines radiation resistance, long-term data storage and low power consumption efficiently and effectively. The three product lines are as follows:
3V3 Parallel EEPROM
- Capacity: 128 Mbit
- Interface: 3.3 V parallel interface
- Temperature: -55 °C to +125 °C
