Periodic Reporting for period 1 - MNEMOSYNE (Magnetic non-volatile Random Access Memory for SPACE with Serial interface)
Berichtszeitraum: 2020-01-01 bis 2021-06-30
non-dependence obviously becomes a key objective of the European Space Strategy while EU satellite industry is struggling against US, Russians and Chinese players.
Therefore, the MNEMOSYNE project coordinated by 3D PLUS has the ambition to develop the first EU independent radiation-hardened high density non-volatile memory (NVM), by using Magnetic RAM (MRAM) technology and the expertise of 6 key partners specialized in radiation hardening and performant components for space and aerospace applications.
Since the beginning of the project, the tasks carried out are essentially focused on the test vehicle, namely, its specification as well as the technical development for its realization.
The test vehicle is a mixed ASIC which contains two blocks, one digital and one analog. These two parts were each specified and developed.
The development of the digital part consists of coding, simulation and verification on an FPGA based emulation board.
The tasks of the definition and the manufacture of this emulation board have been entirely realized. The coding, simulations and verification on board have also been fully realized.
The development of the analog part consists in the design of several analog IPs (oscillator, IO and power management unit-PMU). All these IPs have been designed and simulated. A large implementation phase of all the analog and digital blocks was then done.
Today the test vehicle is ready to be launched in manufacturing at Global Fonderie. Tape-out is scheduled for November 8th.
Eventually, the MNEMOSYNE project aims to develop (design and prototype) the next generation of high density radiation resistant NVM with serial interface based on the most advanced and mature 22nm FDSOI Magnetic RAM (MRAM) technology available on the European market.
Thanks to the FDSOI semiconductor structure, this process naturally offers good radiation tolerance. In addition, MRAM technology is naturally immune to SEU. The main innovations are as follows:
- The first European space NVM RHBD (radiation hardened by design) with a density of more than 1Mb ;
- The world's first RHBD (radiation hardened by design) space NVM with a density greater than 16MB;
- The first European high-performance RHBD space NVM IP core embedded on a sub-65nm process;
- The first next-generation spin transfer torque (STT) MRAM for space application;
- The first RHBD applied on 22nm FDSOI on digital and analog IPs for TID & SEE attenuation;
The development of high density MRAM will reshape the entire memory chip market for the space industry and beyond.
