Abstract :
This paper describes a fault tolerant Solid State Mass Memory (SSMM) for satellite applications. Definition of requirements plays an important role in the architectural solutions selected for the data storing system. The interconnection system proposed is based on a crossbar switch with half duplex links. All the connections have a complete flow control and the path of switched packets is dynamically reconfigurable. A controller tests functionality of each component and handles dynamic data allocation in the memory modules. Memory modules grant data integrity: an original tool developed by the authors derives data coding parameters
