Circuits requiring in excess of 1000k rads-Si are considered strategic rad hard. See SEU . A ccess M emory. A memory that may be written to, or read from any address location in any sequence. Random access in the sense of providing access to any storage location in the memory.
Stores digital bits temporarily and can be rapidly changed as required.
See DRAM and SRAM . Intersil MegaFETS have on-resistance values as low as 10 milliohms. See diode . See mask , photolithography and stepper . This process is expected to extend Intersil's technology lead in rad-hard CMOS beyond that currently provided by TSOS4.
