Les pr\u00e9c\u00e9dentes innovations de Winbond en mati\u00e8re de m\u00e9moire Flash NAND haute performance incluent l’interface Quad SPI-NAND, qui partage les m\u00eames signaux \u00e0 6 broches et la configuration de commande QSPI que la Quad SPI-NOR, et la fonction de lecture continue, capable d’atteindre au taux de transfert de donn\u00e9es continu de 52 Mo\/s \u00e0 une fr\u00e9quence d’horloge de 104 MHz. <\/p>\n

Winbond propose maintenant une nouvelle innovation Flash NAND haute performance avec le lancement de la fonction d’acc\u00e8s s\u00e9quentiel dans ses nouveaux appareils Flash QspiNAND W25NxxxJW haute performance. En mode d’acc\u00e8s s\u00e9quentiel, les produits Flash QspiNAND atteignent le m\u00eame taux maximum de 52 Mo\/s \u00e0 104 MHz qu’en mode de lecture continue, mais avec une nouvelle flexibilit\u00e9 pour configurer le fonctionnement de la puce. Voici les principales nouvelles options :<\/p>\n

\u2022 Capacit\u00e9 \u00e0 utiliser le moteur ECC de l’utilisateur. En mode de lecture continue, un appareil Winbond W25N prend uniquement en charge son propre moteur ECC 1 bit sur la puce. En mode d’acc\u00e8s s\u00e9quentiel, les utilisateurs peuvent impl\u00e9menter une correction d’erreur de 4 bits, 8 bits ou autre lorsqu’il est command\u00e9 par un moteur ECC externe.<\/p>\n

\u2022 Acc\u00e8s \u00e0 l’\u00e9ventail de m\u00e9moire complet \u2013 espace principal et espace compl\u00e9mentaire – avec une commande de lecture seule. Id\u00e9al pour les applications d’occultation de code pour lesquelles une faible latence et un d\u00e9marrage rapide sont particuli\u00e8rement importants.<\/p>\n

\u2022 Plus grande flexibilit\u00e9 pour configurer la disposition des donn\u00e9es en fonction de l’application de l’utilisateur.<\/p>\n

\u00ab En proposant un fonctionnement haut d\u00e9bit avec sa fonction de lecture continue, Winbond avait d\u00e9j\u00e0 fait du Flash QspiNAND une option viable pour les applications de stockage de code, y compris pour l’occultation de code et les op\u00e9rations d’ex\u00e9cution sur place \u00bb, a indiqu\u00e9 Syed S. Hussain, directeur du Marketing de m\u00e9moires Flash chez Winbond Electronics America. \u00ab Avec l’acc\u00e8s s\u00e9quentiel, les utilisateurs peuvent profiter de la m\u00eame vitesse de lecture jusqu’\u00e0 52 Mo\/s tout en impl\u00e9mentant le moteur ECC et les dispositions d’acc\u00e8s aux donn\u00e9es de leur choix. \u00bb<\/p>\n

Les nouveaux produits Flash QspiNAND 1.8 V sont disponibles en 512 Mo, 1 Go et 2 Go. Les versions 3.0 V sont disponibles en 2 Go et 4 Go. Elles sont toutes produites sur le site de fabrication de tranches 12 pouces de la soci\u00e9t\u00e9 \u00e0 Taichung, Ta\u00efwan. <\/p>\n
