Overview: Radiation Tolerant SDRAM space memory

From 512 Mb to 4 Gb, our Radiation Tolerant SDRAM space memory stacks enable high-density and high-speed data transfer solutions. The 3.3 V powered memories feature a wide range of data bus widths: x8b, x16b, x32b, x40b or x64b. They are offered in compact SOP, BGA or QFP package for high resistance Surface Mount (SMT) assembly and withstanding harsh thermal and mechanical environments.

First released in 2003, 3D PLUS SDRAM products are used as processor RAM in a variety of high performance computer boards, and as high density storage memory in Solid State Data Recorder boards. Their use in diverse fields of space applications such as science and deep space missions, Earth observation, launchers and manned space vehicles, navigation satellites, etc. , provides a unique flight heritage. 3D PLUS SDRAM memories have been used on missions such as MSL, Juno, Exomars 2016, Parker Solar Probe, Chandrayaan-3, and others.
