Title
(EN) DATA READ/WRITE METHOD, DEVICE, AND MEMORY HAVING THE SAME
(FR) PROCÉDÉ DE LECTURE/ÉCRITURE DE DONNÉES, DISPOSITIF, ET MÉMOIRE COMPRENANT CELUI-CI
Abstract
(EN)
A data read/write method and device, as well as a dynamic random access memory (DRAM) having the same are disclosed. The method may include: entering a page read/write mode configured by a reserved bit in a mode register of the DRAM; receiving a page read/write command including a page read/write enable command configured by a reserved bit in a read/write command of the DRAM; and performing a page read/write operation according to the page read/write command. This method may allow a greater amount of data to be handled by each read/write command, thereby reducing the number of required read/write commands. As a result, a higher read/write rate and lower power consumption can be achieved.
(FR)
L'invention concerne un procédé et un dispositif de lecture/écriture de données, ainsi qu'une mémoire vive dynamique (DRAM) les comprenant. Le procédé peut comprendre les étapes suivantes : passage dans un mode de lecture/écriture de page configuré par un bit réservé dans un registre de mode de la DRAM ; réception d'une instruction de lecture/écriture de page comprenant une instruction d'autorisation de lecture/écriture de page configurée par un bit réservé dans une instruction de lecture/écriture de la DRAM ; et exécution d'une opération de lecture/écriture de page en fonction de l'instruction de lecture/écriture de page. Ce procédé peut permettre de gérer une plus grande quantité de données par chaque instruction de lecture/écriture, ce qui réduit le nombre d'instructions de lecture/écriture exigées. Un taux de lecture/écriture supérieur et une consommation d'énergie inférieure peuvent ainsi être obtenus.
