Maxwell Technologies鈥?79C0408 multi-chip module (MCM)
memory features a greater than 100 krad (Si) total dose toler-
ance, depending upon space mission. Using Maxwell Technol-

廬 MCM
packaging technology, the 79C0408 is the first radiation-hard-
ened 4 Megabit MCM EEPROM for space applications. The
79C0408 uses four 1 Megabit high-speed CMOS die to yield a
4 Megabit product. The 79C0408 is capable of in-system elec-
trical Byte and Page programmability. It has a 128 bytes Page
Programming function to make its erase and write operations
faster. It also features Data Polling and a Ready/Busy signal to
indicate the completion of erase and programming operations.
In the 79C0408, hardware data protection is provided with the
RES pin, in addition to noise protection on the WE signal.
Software data protection is implemented using the JEDEC
optional standard algorithm.

廬 packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, the R

廬 package provides
greater than 100 krad (Si) radiation dose tolerance. This prod-
uct is available with screening up to Class K.
