Overview: Radiation Tolerant SDRAM space memory

3D PLUS offers a range of high-performance, Radiation Tolerant SDRAM space memory solutions tailored to meet the demanding requirements of space applications. Available in capacities from 512 Mb to 4 Gb, our SDRAM memory stacks enable high-density and high-speed data transfer, essential for the rigorous demands of space missions. These 3.3 V powered memories come with versatile data bus widths, including x8b, x16b, x32b, x40b, and x64b, making them adaptable to various system architectures.

Our Radiation Tolerant SDRAMs are engineered to withstand harsh thermal and mechanical environments, ensuring reliable performance in space. They are packaged in space-optimized SOP, BGA, or QFP forms, designed for high resistance Surface Mount (SMT) assembly.

The 3D PLUS SDRAM Flight Heritage

Since their first release in 2003, 3D PLUS SDRAM products have been trusted as processor RAM in high-performance computer boards and as high-density storage memory in Solid State Data Recorder boards. These memories have a proven track record in a diverse array of space applications, including scientific and deep space missions, Earth observation, launchers, manned space vehicles, and navigation satellites. This extensive flight heritage underscores their reliability and performance.

3D PLUS SDRAM memories have been integral to numerous high-profile missions such as MSL, Juno, Exomars 2016, Parker Solar Probe, and Chandrayaan-3. Their robust design and radiation tolerance make them the preferred choice for mission-critical space applications, ensuring data integrity and system reliability in the most challenging environments.
