Abstract

We describe X2000, a new concept in JPL´s avionics development. Further, a need for non-volatile radiation hardened memory is brought forth. A 1 Megabit/in² memory density specification: 10 year lifetime, 1-MegaRad total ionizing radiation dose survivability, and >10¹³ write cycles is drawn for such NASA´s missions as Europa Orbiter as the first delivery for X2000. We present an overview related with the Government development effort for three such new memory technologies
