DDR4 ideal Companion-chips for Space grade devices such as processors, FPGAs SiP solutions & beyond…

The 4/8GB Radiation Tolerant DDR4 Memory Multi-Chip Package (MCP) is a Ultra High Density Memory Solution, targeting Space Embedded Systems & Applications.
This space-grade DDR4 memory enables elevated levels of performance, while taking up minimal board real estate – something that is certain to be of value in highly space-constrained, densely-packed satellite designs. It can be used in conjunction with processors and FPGAs having a DDR4 controller, and is also available embedded on Teledyne e2v Space version of Qormino® Common Compute Platform together with a Space version of LS1046 quad-core processor (QLS1046-4GB). Together with the DDR4 memory, a complete radiation and application datapackage is available allowing designers to develop their board quickly and with minimum risk.
