DESCRIPTION:

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 1.5 Gigabits and

speeds up to 100 Megahertz. SDRAMs represent a sig-

nificant advantage in memory technology over traditional

DRAMs 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

Maxwell Technologies’ patented RAD-PAK

® 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, RAD-PAK

® provides greater than 100 krads(Si)

radiation dose tolerance. This product is available with

screening up to Maxwell Technologies self-defined Class

K.
