These SDRAM based products offer a high density memory solution that meets wide data bus requirements necessary for high reliability defense and avionics applications.

The Magneto-resistive Random Access Memory (MRAM) stores data using magnetic polarization rather than electric charge, which brings the MRAM unlimited Read/Write endurance and Single Event Upset (SEU) immune characteristics.

PROM memories are a One-Time-only programmable non volatile memories. 32Mb to 64 Mb Radiation Tolerant PROM stacks are available in a variety of temperature ranges, organized x8 and with a power supply of 3.3V.

The EEPROM (Electrically Erasable and Programmable ROM) stacks enable the programming of high-density non-volatile memory both while installed and while in orbit.

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.

The leading supplier of high-reliability electronic components for space applications has announced that the CASPEX 4M space camera head has been chosen to represent the Yvelines department at the 5th Grande Exposition du Fabriqué en France, which will take place from 15 to 16 November at the Élysée Palace.

In space applications, high-performance computing systems must withstand extreme conditions. Radiation Tolerant DDR4 memories excel in speed, bandwidth, and energy efficiency, making them ideal for critical data storage and access…
