ESCRIPTION
:
Maxwell Technologies’ 79LV2040 multi-chip module (MCM)
memory features a greater than 100 krad (Si) total dose toler-
ance, dependent upon orbit. Using Maxwell Technologies’ pat-
ented radiation-hardened R

MCMpackaging
technology, the 79LV2040 is the first radiation-hardened 8
megabit MCMEEPROMfor space application. The 79LV2040
uses twenty 1 Megabit high speed CMOS die to yield a 20
megabit product. The 79LV2040 is capable of in-systemelec-
trical byte and page programmability. It has a 128 x 40 page
programmng function to make the erase and write operations
faster. It also features Data Polling and a Ready/Busy signal to
indicate the completion of erase and programmng operations.
In the 79LV2040, hardware data protection is provided with
the RES pin, in addition to noise protection on the WE signal
and write inhibit on power on and off. Software data protection
is implemented using the JEDEC optional standard algorithm
