Commercially fabricated radiation hardened 4Mbit SRAM

Survivability of memory integrated circuits is critical to the successful completion of military, civilian, and commercial space applications. Radiation hardened 4 Mbit SRAMs have been developed for these purposes. Aeroflex Colorado Springs, with support from the Air Force Research Laboratory, has developed, tested, and qualified hardened 4Mbit SRAMs in two configurations 512 K×8 and 128 K×32. Unlike other hardened 4Mbit SRAMs, Aeroflex exploits high-volume commercial manufacturing methods to achieve unprecedented low power and electrical performance. Other inherent benefits to using mature high-volume commercial fabrication processes include high yield and reliability at reduced manufacturing costs.
