Space-grade memory: 72-bit-wide DDR2 in BGA package

April 30, 2013 // By Julien Happich
The 3D2D4G72UB3478 is what 3D Plus claims to be the first space grade 72b wide DDR2 memory module, organized as 64M x72b and particularly suited for use in high reliability, high performance and high density system applications.

The 4.6 Gbit, 29 x 19 x 7.6 mm device weighs 6g and is packaged in a 191 BGA available with lead-free or leaded balls. It is radiation tolerant with a single event latch-up (SEL) threshold of over 60 Mev.cm 2/mg. Available in industrial and specific temperature range for high reliability space applications, the space-qualified wide data bus DDR2 memory module is more specifically targeted for the Virtex-5QV FPGAs and DDR2 interface IP. The Virtex-5QV chips, which are Rad-Hard by design, are being rapidly adopted by the Space community. The memory module operates from 1.8V +/- 0.1V and supports data rates of 400, 553 and 667 Mbps.
