Teledyne e2v announces space qualification for radiation-hardened 8-gigabyte DDR4 memory for spacecraft
GRENOBLE, France – Teledyne e2v, a Teledyne Technologies company in Grenoble, France, is announcing space qualification of the company's 8-gigabyte space DDR4 memory for satellites and manned spacecraft.
Qualification includes upscreening for temperature cycling, construction analysis, and C-SAM; confocal scanning acoustic microscopy; preconditioning; humidity; and radiation tests.
This radiation-hardened high-density 8-gigabyte DDR4 memory provides the same form factor and pin compatibility of the smaller 4-gigabyte DDR4 option for next-generation designs.
Space missions such as Earth observation require tens of-gigabyte of data storage. Modern satellite payloads shift vast amounts of data minute by minute, hour by hour. Moreover, modern micro- and cube-sats place huge constraints on system size and power.
The fast 8-gigabyte DDR4 memory supports a transfer rate of 2.4 billion transfers per second. It is single-event latch-up (SEL) immune up to 60 MeV.cm²/mg. Moreover, the device provides 100 krad total ionizing dose (TID).
The 8-gigabyte device comes in a package matching the size of the previous 4-gigabyte version -- 15 by 20 by 1.92 millimeters -- thus doubling storage density while maintaining pinout compatibility.
