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 memory 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 significant 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 precharge time
Maxwell Technologies’ patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit 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.
