Introducing the new radiation tolerant 80-bit DDR4 space qualified memory from 3D PLUS

We at MSA Components are excited to introduce the new radiation resistant, space-qualified 80-bit DDR4 memory 3D4D64G80LB2860, the latest addition to the DDR4 family from 3D PLUS. The 3D4D64G80LB2860 offers a 64 Gbit with 80 bit bus width and can typically be used as 64 bit data + 16 bit ECC, which significantly increases the reliability of the overall system. Therefore, this radiation-tolerant DDR4 is particularly suitable for system applications with high reliability, performance and density, such as computer memory.

The 80-bit DDR4 memory as part of the DDR4 ecosystem

The 3D4D64G80LB2860 is also part of the DDR4 ecosystem from 3D PLUS. In these, the DDR4 SDRAM products for space applications are used as processing memory alongside the latest processors, FPGAs, in a variety of computer boards, providing a fully space-qualified memory subsystem solution. They work synergistically in an ecosystem with two additional elements, providing a space-qualified DDR4 solution that is unmatched in terms of performance and radiation reliability. 

DDR4 memory for space applications

In space applications, the demand for high-performance computing systems that can withstand extreme conditions is paramount. Radiation-tolerant DDR4 memory offers significant advantages in terms of speed, bandwidth and power efficiency, making it ideal for storing and accessing critical data for satellite communications, on-board processing and mission-critical operations. Our supplier 3D PLUS has a long history of providing radiation-tolerant memory for data processing from SDRAM to DDR and can offer other suitable radiation-tolerant DDR4 memory solutions in addition to the new 80-bit DDR4 memory 3D4D64G80LB2860.
