A storage device. In some embodiments, the storage device includes a storage interface, configured to be connected to a host computer, a processing circuit, and persistent storage media. The processing circuit may be configured to: read first data from the persistent storage media in response to a read command received through the storage interface; transmit second data through the storage interface, the second data being based on the first data; receive a write command, with third data, through the storage interface; write fourth data, based on the third data, to the persistent storage media; and perform a cryptographic operation on the first data or on the third data.

SSD content encryption and authentication

A non-volatile memory system performs data operations efficiently for a host system by having a multi-layered architecture. The system includes multiple local controllers that are connected to an array of non-volatile memories, a master controller connected to the multiple local controllers, and an internal processing unit that communicates with the master controller. The internal processing unit receives data operation requests from the host system and generates groups of related operations. A group of related operations include a set of common addresses and multiple commands. The internal processing unit sends a group of related operations to the master controller, which in turn broadcasts the group of related operations to the local controllers, by first broadcasting addresses to the local controllers, broadcasting a first command to the local controllers, and then broadcasts a second command to the local controllers while the local controllers are still executing the first command.

Apparatus, system, and method of look-ahead address scheduling and autonomous broadcasting operation to non-volatile storage memory

An improved way of communicating data operation commands within a non-volatile storage controller is presented. The non-volatile storage controller includes an internal processing unit that is communicatively coupled with an associated host system, a master controller, and a plurality of local controllers that are communicatively coupled with a non-volatile memory. Upon receiving a series of data operations commands from the host system, the internal processing unit is configured to apply address shadowing when communicating the series of commands to the master controller such that the internal processing unit does not need to repetitively send the same set memory addresses to the master controller when issuing the series of commands.
