Full textPhase change memory (PCM) is part of the strategy to develop non-volatiles memories embedded in advanced technology nodes (sub 28nm). Indeed, Flash-NOR memory is becoming more and more expensive to integrate in technologies with high permittivity dielectrics and metallic gates. The main objective of this thesis is therefore to realize tests vehicles in order to study an innovative PCM + OTS memory point and to propose solutions to fill its gaps and limitations according to the envisaged applications. The study is based on two different technologies: HCMOS9A and P28FDSOI. The first one is used as support for the development of a technological validation vehicle of the OTS+PCM memory point. The second one is used to demonstrate the surface obtained with an aggressive sizing of the memory point. Finally, an optimized readout circuit for this memory point has been realized allowing the compensation of leakage currents as well as the regulation of the bias voltages of the matrix during the reading

Nous utilisons pour résoudre ce problème un schéma multi-niveaux dont nous avons parallélisé les phases de contraction et d'expansion.
Nous avons ainsi introduit pour la phase de contraction un nouvel algorithme de gestion des conflits d'appariements distants, tout en
améliorant les algorithmes déjà existants en leur associant une phase
de sélection des communications les plus utiles.
Concernant la phase d'expansion, nous avons introduit la notion de graphe bande qui permet de diminuer de manière très conséquente la taille du problème à traiter par les algorithmes de raffinement. Nous avons généralisé l'utilisation de ce graphe bande aux implantations séquentielles et parallèles de notre outil de partitionnement Scotch.
Grâce à la présence du graphe bande, nous avons proposé une utilisation nouvelle des algorithmes génétiques dans le cadre de
l'expansion en les utilisant comme heuristiques parallèles de raffinement de la partition.

Full textLarge covariance matrices play a fundamental role in the multivariate analysis and high-dimensional statistics. Since the pioneer’s works of Marcenko and Pastur (1967), the asymptotic behavior of the spectral measure of such matrices associated with N independent copies of n observations of a sequence of iid random variables is known: almost surely, it converges in distribution to a deterministic law when N and n tend to infinity at the same rate. More recently, Merlevède and Peligrad (2016) have proved that in the case of large covariance matrices associated with independent copies of observations of a strictly stationary centered process which is square integrable and satisfies some weak regularity assumptions, almost surely, the empirical spectral distribution converges weakly to a nonrandom distribution depending only on the spectral density of the underlying process. In particular, if the spectral density is continuous and bounded (which is the case for linear processes with absolutely summable coefficients), the limiting spectral distribution has a compact support. However, if the underlying stationary process exhibits long memory, the support of the limiting distribution is not compact anymore and studying the limiting behavior of the eigenvalues and eigenvectors of the associated large covariance matrices can give more information on the underlying process. This thesis is in this direction and aims at studying the asymptotics and the fluctuations of the largest eigenvalues of large covariance matrices associated with stationary processes exhibiting long memory. In the case where the underlying stationary process is Gaussian, the study can be simplified by a linear model whose underlying population covariance matrix is a Hermitian Toeplitz matrix. In the case of stationary Gaussian processes exhibiting long memory, we then show that the fluctuations of the largest eigenvalues suitably renormalized are Gaussian. This limiting behavior shows a difference compared to the one when large covariance matrices associated with short memory processes are considered. Indeed in this last case, the fluctuations of the largest eigenvalues suitably renormalized follow asymptotically the Tracy-Widom law. To prove our results on Gaussian fluctuations, additionally to usual techniques developed in random matrices analysis, a deep study of the eigenvalues and eigenvectors behavior of the underlying Toeplitz matrix is necessary. In particular, we show that in the case of long memory, the largest eigenvalues of the Toeplitz matrix converge to infinity and satisfy a property of “multiple spectral gaps”. Moreover, we prove a delocalization property of their associated eigenvectors. In this thesis, we are also interested in the universality of our results in the case of the simplified model and also in the case of large covariance matrices when the Toeplitz matrices are replaced by bloc diagonal matrices

Full textFast matrix multiplication (FMM) algorithms to multiply two n x n matrices reduce the asymptotic operation count from O (n³) of the traditional method to O (n². Xx), thus the parallelization of FMM algorithms always gives remarkable results in comparison to the parallel matrix multiplication algorithms based on traditional method. Within this parallelization, the application of FMM algorithms at the inter-processor level requires us to solve more difficult problems in designing but it forms the most effective algorithms. To use FMM algorithms at the inter-processor level, the most significant point is to determine the submatrices after having recursively executed r times the FMM formulas and then to find the result matrix from the products of these sub matrices. With a definite value of r, we can manually solve this problem like in the previous works with r=1,2, but the solution for the general case has not been found. In this PhD work, by combining our general solution for this problem with a good storage map of submatrices to processor, and with the parallel matrix multiplication algorithms based on traditional method (1D-systolic, 2D-systolic, Fox (BMR), Cannon, PUMMA, BiMMeR, SUMMA, DIMMA. . . ) we have a general scalable parallelization of FMM algorithms on distributed memory computers. Complexity analyses show that our algorithms should be faster than the parallel algorithms based on traditional method when the matrix size is large and our work is relevant to exploit better algorithms when the recursion level is large enough. Experimental results on Fujitsu Siemens Computers/hpcLine confirm the theoretical result by showing that our algorithms perform better than Cannon's Algorithm from 1. 2 to 2. 4 times for matrices of size 8196 x 8196

Full textDirect methods for solving sparse linear systems are known for their large memory requirements that can represent the limiting factor to solve large systems. The work done during this thesis concerns the study and the optimization of the memory behaviour of a sparse direct method, the multifrontal method, for both the sequential and the parallel cases. Thus, optimal memory minimization algorithms have been proposed for the sequential case. Concerning the parallel case, we have introduced new scheduling strategies aiming at improving the memory behaviour of the method. After that, we extended these approaches to have a good performance while keeping a good memory behaviour. In addition, in the case where the data to be treated cannot fit into memory, out-of-core factorization schemes have to be designed. To be efficient, such approaches require to overlap I/O operations with computations and to reuse the data sets already in memory to reduce the amount of I/O operations. Therefore, another part of the work presented in this thesis concerns the design and the study of implicit out-of-core techniques well-adapted to the memory access pattern of the multifrontal method. These techniques are based on a modification of the standard paging policies of the operating system using a low-level tool (MMUM&MMUSSEL)

Full textFlexible electronics market revenue is expected to exceed $10B by 2020. Duento their mechanical flexibility, flexible circuits will enable numerous developmentsnin various fields from internet-of-things applications to large area electronics. Besides logic devices, memory is the second fundamental component of any electronic system. During this thesis, we aimed at developing nonvolatile memories referred as CBRAM (Conductive-Bridge Random Access Memories) for flexible electronics applications. These devices consist in a simple Metal-Electrolyte-Metal structure. The memory effect relies on resistance switching due to the formation/dissolution of a metallic conductive filament within a solid electrolyte. The use of chalcogenide glasses or polymers layers as solid-electrolytes offers many opportunities for future for flexible applications. In a first part, memory devices based on of GeS$_x$ and de Ge$_X$Sb$_Y$Te$_Z$ solid electrolytes on silicon substrates we fabricated and electrically tested. Experimental results were then confronted to an electro-thermal model, based on ionic current, developed during this thesis. The final chapter of this manuscript is devoted to the development of flexible memories
