ESCRIPTION
:
Maxwell Technologies’ Synchronous Dynamic Random
Access Memory (SDRAM) is ideally suited for space
applications requiring high performance computing and
high density memory storage. As microprocessors
increase in speed and demand for higher density mem-
ory escalates, SDRAM has proven to be the ultimate
solution by providing bit-counts up to 1 Gigabits and
speeds up to 100 Megahertz. SDRAMs represent a sig-
nificant advantage in memory technology over traditional
SRAMs including the ability to burst data synchronously
at high rates with automatic column-address generation,
the ability to interleave between banks masking pre-
charge time, and the ability to randomly change column
address during each clock cycle.
Maxwell Technologies’ patented R

packaging
technology incorporates radiation shielding in the micro-
circuit package. It eliminates the need for box shielding
for a lifetime in orbit or space mission. In a typical GEO
orbit, R
