A Fault-Tolerant 176 Gbit Solid State Mass Memory Architecture

چکیده
This paper presents a new Solid State Mass Memory (SSMM) suitable for space applications. The memory reliability is increased by using two different approaches. Firstly, memory mass fault-tolerance, with respect to hard failures, is obtained by using a fine-granularity hierarchical structure with a certain level of redundancy. A second strategy used for facing soji errors is based on Error Correction Codes (ECC) and periodic memory washing. A performance index has been developed for evaluating the main parameters of the SSMM architecture. This index takes into account the ECC capability, the memory weight and reliability, allowing to relate them to the required overhead.

We introduce a nanowire-based, sublithographic memory architecture tolerant to transient faults. Both the storage elements and the supporting ECC encoder and corrector are implemented in dense, but potentially unreliable, nanowirebased technology. This compactness is made possible by a recently introduced Fault-Secure detector design [18]. Using Euclidean Geometry error-correcting codes (ECC), ...

متن کاملDesign of Fault-Tolerant Solid State Mass Memory
This paper describes a novel architecture of fault tolerant Solid State Mass Memory (SSMM) for satellite applications. Mass memories with low-latency time, high throughput, and storage capabilities cannot be easily implemented using space qualified components, due to the inevitable technological delay of these kind of components. For this reason, the choice of Commercial Off The Shelf (COTS) co...
