3D PLUS Space Radiation Tolerant DDR4 SDRAM modules inherit the company’s extensive experience as a space memory supplier and manufacturer, from SRAM, SDRAM, DDR1 and DDR2 through to DDR3.
The 3D PLUS space qualified DDR4 SDRAM offers higher speed and lower power consumption than DDR3 SDRAM. Available in densities from 16 Gb to 64 Gb, the Radiation Tolerant DDR4 SDRAM modules are organised as x48b, x72b or x80b and operate with a 1.2 V power supply. Like the DDR3 space memories, the DDR4 modules feature an optimised design with decoupling capacitors and termination resistors embedded in the module. They are offered in a BGA package for high-reliability Surface Mount Technology (SMT) assembly and for withstanding harsh thermal and mechanical environments.
The DDR4 SDRAM products for space applications are used as processing memories alongside the latest processors and FPGAs, in a variety of computer boards. They operate as part of a space-qualified DDR4 ecosystem comprising two additional 3D PLUS companion chips, providing a complete radiation-tolerant DDR4 memory solution:
The Radiation Intelligent Memory Controller (RIMC) for DDR4 – 3DIPMC0815 A fully configurable DDR4 SDRAM memory controller designed to work with 3D PLUS DDR4 modules to provide an overall radiation-hardened memory solution. This IP core offers Single Event Upset (SEU) and Single Event Functional Interrupt (SEFI) mitigation for DDR4 operating in radiation-hazardous environments.
A radiation hardened by design Termination Regulator DDR4 TR– 3DPM0424
A radiation-hardened-by-design termination regulator that provides all power requirements for DDR4 VTT bus designs. It reduces power dissipation while dramatically improving signal integrity.
