Abstract
A method includes, in a data storage device including a non-volatile memory, performing receiving, from a host device in a master-slave configuration with the data storage device, a first notification corresponding to a first read command. The method also includes storing, based on the first notification, a first entry in a notification queue. The first entry corresponds to the first read command. The method further includes storing first data corresponding to a second command at a location of the non-volatile memory. The location corresponds to an address to be read upon execution of the first read command. The second command is associated with an operation to be performed by the host device. The method includes, after storing the second data, setting an indicator corresponding to the first entry. The set indicator conveys that the data storage device is ready to execute the first read command.
