Radiation Hardened EEPROMs
Northrop Grumman offers the only Radiation Hardened EEPROMs with the ability to re-write to memory.
The radiation hardened robustness of the design (performed by Sandia National Laboratories) and fabrication process is flight proven with more than 10,000 radiation hardened EEPROM devices previously delivered to production systems. This product line offers the only solid-state reprogrammable nonvolatile memory available today that is inherently radiation hardened. No special shielding, specialized packages, redundant devices, or special power down is required to operate these devices in severe radiation environments. Users have the ability to re-write to memory more than 10,000 times with retention of 10 years.
