Overview

DDR3 SDRAM is the upgrade of DDR2 Memory with higher speed and lower power consumption. From 16 Gb to 24 Gb, our Radiation Tolerant DDR3 SDRAM modules are organized as x16b, x48b or x72b, and with a 1.35 V or 1.5 V power supply. Our DDR3 modules embed decoupling capacitors for excellent signal integrity and additional real estate savings on the users’ PCBs. They are offered in standard BGA package for high resistance Surface Mount (SMT) assembly and withstanding harsh thermal and mechanical environments.

Released on the space market in 2018, our DDR3 SDRAM products are used as processing memory in a variety of high performance computer boards. They operate synergistically in an Ecosystem with two additional elements, providing  all-in-one, fully space qualified and radiation immune DDR3 memory solution. The DDR3 memory companion chips are:

  • The Radiation Intelligent Memory Controller (RIMC) for DDR3 (3DIPMC0744) is a fully configurable DDR3 SDRAM memory controller designed to work with 3D PLUS DDR3 modules to provide an overall radiation hardened memory solution. This IP core offers Single Event Upset (SEU) mitigation and Single Event Functional Interrupt (SEFI) protection to DDR3 operating in radiation-hazard environments.
  • A radiation hardened by design Termination Regulator DDR3 TR (3DPM0385). It provides enhanced termination and impedance adaptation, dramatically improving signal integrity.

Our DDR3 have been use in diverse missions such as: EMIT, and others.
