Abstract

Selon l'invention, des fichiers de données sont attribués à des adresses dans un ou plusieurs blocs logiques d'une interface d'espace adresse logique continu (interface LBA) de type courant d'un système de mémoire flash comprenant des blocs de cellules de mémoire physique. Cette attribution peut être réalisée par le dispositif hôte qui en général, mais pas nécessairement, produit les fichiers de données. Le nombre de blocs logiques contenant des données d'un type quelconque est régulé de façon à réduire l'ampleur de la fragmentation des données de fichier dans les blocs de mémoire physique, ce qui permet de maintenir un bon rendement de mémoire. L'hôte peut configurer les blocs logiques de l'espace adresse en réponse à l'apprentissage des propriétés physiques d'une mémoire à laquelle il est connecté.
