Abstract
(EN)
A data storage device includes a memory, a controller, and a communication bus coupled to the memory and to the controller. The controller is configured to send a read-write command and write data to the memory via the communication bus. The read-write command indicates an address of requested data to be read from the memory. The controller is further configured to receive the requested data read from the memory. Communicating the requested data over the communication bus overlaps the write data being stored into the memory.

Selon l'invention, un dispositif de stockage de données comprend une mémoire, un gestionnaire, et un bus de communication accouplé à la mémoire et au gestionnaire. Le gestionnaire est configuré pour envoyer une commande de lecture-écriture et écrire des données dans la mémoire par l'intermédiaire du bus de communication. La commande de lecture-écriture indique une adresse de données demandées à lire à partir de la mémoire. Le gestionnaire est de plus configuré pour recevoir les données lues à partir de la mémoire. La communication des données demandées sur le bus de communication est superposée au stockage des données d'écriture dans la mémoire.
