New memory production modern technologies introduce new classes of faults usually referred to as Dynamic Memory Faults. Although some hand-made March Tests to deal with these new faults have been published, the problem of automatically generate March Tests for Dynamic Faults has still to be addressed. In this paper we propose a new approach to automatically… (More)
The Functional BIST approach is a rather new BIST technique based on exploiting embedded system functionality to generate deterministic test patterns during BIST. The approach takes advantages of two well-known testing techniques, the arithmetic BIST approach and the reseeding method. The main contribution of the present paper consists in formulating the… (More)
Embedded microprocessor cache memories suffer from limited observability and controllability creating problems during in-system tests. This paper presents a procedure to transform traditional march tests into software based self test programs for setassociative cache memories with LRU replacement. Among all the different cache blocks in a microprocessor,… (More)
This paper presents a BIST architecture, based on a single micro-programmable BIST Processor and a set of memory Wrappers, designed to simplify the test of a system containing many distributed multi-port SRAMs of different sizes (number of bits, number of words), access protocol (asynchronous, synchronous), and timing.
Despite great advances in discovering cancer molecular profiles, the proper application of microarray technology to routine clinical diagnostics is still a challenge. Current practices in the classification of microarrays' data show two main limitations: the reliability of the training data sets used to build the classifiers, and the classifiers'… (More)
In spite of the mature cell structure, the memory controller architecture of Multi-level cell (MLC) NAND Flash memories is evolving fast in an attempt to improve the uncorrected/miscorrected bit error rate (UBER) and to provide a more flexible usage model where the performance-reliability trade-off point can be adjusted at runtime. However, optimization… (More)
What is the probability that the execution state of a given microprocessor running a given application is correct, in a certain working environment with a given soft-error rate? Trying to answer this question using fault injection can be very expensive and time consuming. This paper proposes the baseline for a new methodology, based on microprocessor error… (More)
This paper presents an innovative algorithm for theautomatic generation of March Tests. The proposedapproach is able to generate an optimal March Test foran unconstrained set of memory faults in very lowcomputation time.
