Electrically Erasable and Programmable ROM (EEPROM) enable on-board and in-orbit programming capability as non volatile memories. Based on the very rugged NMOS memory cell technology, our Radiation Tolerant EEPROM stacks feature high endurance and high data retention time. The 3.3 V or 5.0 V powered memories feature a wide range of data bus widths: x8b, x32b or x40b. They are offered in compact SOP package for high resistance Surface Mount (SMT) assembly and withstanding harsh thermal and mechanical environments.
Released in 2003, 3D PLUS EEPROM products are used as processor’s Boot and Program ROM in a variety of high performance computer boards. Their use in diverse fields of space applications such as science and deep space missions, Earth observation, launchers and manned space vehicles, navigation satellites, etc. , provides a unique flight heritage. These memory modules have been used on missions such as Exomars 2016, Change’5, H-IIA/H-IIB, Chandrayaan-3, Orion Artemis, and others.
EEPROM is not recommended for new design, instead we recommend MRAM which is a high speed, unlimited read and write endurance and non- volatile random access memory. EEPROM and MRAM memories are both byte-addressed, with active LOW control signals. It means that both protocols are basically compatible. Our MRAM memories present excellent radiation performances , thus they are suitable to replace our EEPROM memories.
