The Radiation Intelligent Memory Controller is a fully configurable DDR2/3/4 SDRAM memory controller IP core designed to work with 3D PLUS DDR2/3/4 memory modules to achieve radiation tolerance improvement. The RIMC contains all standard functions of a DDR2/3/4 memory controller for data width applications from 8b up to 144b. It includes also additional functions, such as Single Event Upset (SEU) mitigation and Single Event Functional Interrupt (SEFI) protection to be able to work in radiation environments. In addition to the memory controller IP within the RIMC IP core, the user can either select PHY IPs provided in the IP core or develop its own PHY IP.
