In space applications, high-performance computing systems must withstand extreme conditions. Radiation Tolerant DDR4 memories excel in speed, bandwidth, and energy efficiency, making them ideal for critical data storage and access in satellite communication, onboard processing, and mission-critical operations. 3D PLUS, with a long space heritage of providing radiation tolerant memory for data processing from the SDRAM to DDR4, introduces the 3D4D64G80LB2860, the latest in their DDR4 family. Offering 64 Gbit capacity with an 80-bit bus width, it enhances overall system reliability with a 64-bit data plus 16-bit ECC configuration.
The 3D4D64G80LB2860 is a high-speed, highly integrated DDR4 Synchronous Dynamic RAM designed for space applications. This 64 Gbit DDR4 is embedding 10 chips of 8 Gbit and 8 bus width. It can be typically used as 64 bits data + 16 bits ECC.
This organization allows the use of ECC to prevent data loss (8 bits of ECC are used tocorrect 8 bits of data). Furthermore, independent RESET capability is offered for customer to fine tune SEE mitigation.
Thus, this radiation tolerant DDR4 is particularly well suited for high reliability, performance, and density system applications such as computing memories. It is part of 3D PLUS’s DDR4 ecosystem, providing fully space qualified memory subsystem solution.
Included in the DDR4 ecosystem from 3D PLUS
DDR4 SDRAM products designed for space applications serve as processing memories alongside the latest processors and FPGAs in various computer boards. They function synergistically within an ecosystem that includes two additional components, delivering an unparalleled space-qualified DDR4 solution in terms of performance 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 integrate with 3D PLUS DDR4 modules, offering a comprehensive radiation-hardened memory solution. This IP core provides Single Event Upset (SEU) and Single Event Functional Interrupt (SEFI) mitigation for DDR4 memory operating in radiation-prone 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.
