Fault-tolerant solid state mass memory for satellite applications

This paper presents a structure of solid state mass memories based on DRAMs, able to collect a large amount of measurement results. It is based on a suitable ECC code to improve the tolerance of the solid state memories to soft and hard errors. This memory will be tested in a satellite designed for a scientific mission. The implementation aspects of ECC are also discussed, and the relation between the code properties and MTBF of the disk are examined in some detail.
