3D Plus – Memory DDR4 SDRAM

The Memory DDR4 SDRAM are featuring higher speed and lower consumption than DDR3 SDRAM.

From 16 Gb to 64 Gb, our Radiation Tolerant DDR4 SDRAM modules are organized as x48b or x72b, and with a 1.2 V power supply.

Similar to the DDR3 memories, our DDR4s feature an optimized design with decoupling capacitors and termination resistors embedded in the module.

They are offered in BGA package for high resistance Surface Mount (SMT) assembly and withstanding harsh thermal and mechanical environments.

The DDR4 SDRAM products are used as processing memories alongside the latest processors, FPGAs, in a variety of computers boards.

They operate synergistically in an Ecosystem with two additional elements, providing  a space qualified DDR4 solution that is unmatched in terms of performances and radiation reliability.

The DDR4 memory companion chips are:

• The Radiation Intelligent Memory Controller (RIMC) for DDR4 (3DIPMC0815) is 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 to DDR4 operating in radiation-hazard environments.
• A radiation hardened by design Termination Regulator DDR4 TR (3DPM0424). This companion chip provides all power requirements for DDR4 VTT bus designs. It reduces power dissipation while dramatically improving signal integrity.

The DDR4s inherit 3D PLUS’s experience as  space memory supplier and manufacturer from SRAM, SDRAM, DDR1, DDR2 to DDR3.
