View Edit Delete	US8762658B2	FIG. 7 is a schematic flow chart diagram illustrating an embodiment of a method 700 for managing data in a solid-state storage device 102 using a bank interleave in accordance with the present invention. The method 700 begins 702 and the bank interleave controller 344 directs 604 one or more commands to two or more queues 410, 412, 414, 416. Typically the agents 402, 404, 406, 408 direct 704 the commands to the queues 410, 412, 414, 416 by command type. Each set of queues 410, 412, 414, 416 includes a queue for each command type. The bank interleave controller 344 coordinates 706 among the banks 214 execution of the commands stored in the queues 410, 412, 414, 416 so that a command of a first type executes on one bank 214a while a command of a second type executes on a second bank 214b, and the method 700 ends 708.	219	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In one embodiment, the token directive transmission module 1004 transmits a token directive without a data segment token. In this embodiment, the token directive includes instructions and information for the storage device 150 to create a data segment token. In another embodiment, the token directive transmission module 1004 transmits a token directive that includes a data segment token. In this embodiment, the storage device 150 is capable of recognizing that the data segment token received with the token directive represents a data segment and takes appropriate action to store the data segment token such that the data segment token represents the data segment rather than merely storing the data segment token as ordinary data.	256	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	The apparatus includes a token directive transmission module 1004 that transmits the token directive to the storage device 150. Typically, the token directive transmission module 1004 transmits the token directive as part of a storage request. The storage request may be in the form of an object request, a data request, or other form known to those of skill in the art. Where the token directive generation module 1002 generates a secure erase directive, the token directive transmission module 1004 transmits the secure erase directive to the storage device 150. Where the token directive generation module 1002 generates an erase encryption key command, the erase encryption key command is transmitted, where necessary, to another device to execute the command.	255	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In one embodiment, a token directive includes the data segment token and the token directive transmission module 1004 transmits the data segment token with the token directive. In another embodiment, a token directive does not include the data segment token and includes a command for the storage device 150 to generate the data segment token. In this embodiment, the token directive transmission module 1004 transmits the token directive with the command to generate a data segment token, but does not transmit a data segment token.	254	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In one embodiment, erasing the encryption key includes erasing the encryption key from the requesting device. In another embodiment, erasing the encryption key includes erasing the encryption key from a server, key vault, or other location where the encryption key is stored. Erasing the encryption key may include replacing the encryption key with other data or with a series of characters so that the encryption key cannot be recovered in any way. Erasing the encryption key typically makes the existing data on the storage device 150 non-recoverable where an encryption routine was used to encrypt the existing data that is robust enough to thwart attempts to decrypt the existing data. The request to overwrite the existing data could be a secure erase directive where the data is overwritten for security reasons, a request to overwrite data to erase the data, a request that seeks to replace the existing data with the repeated, identical characters or character strings, or the like. In one embodiment, a secure erase directive causes devices to both securely erase the encryption key and securely erase the existing data. In one embodiment, erasure of the encryption key may allow secure erasure of the data on the storage device 150 to be postponed until a garbage collection process erases the data as part of a storage space recovery process. One of skill in the art will recognize other ways to erase an encryption key and other ways to receive a request to overwrite existing data.	253	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	Data may be encrypted and then stored on a storage device 150 where encryption is accomplished using an encryption key received by the storage device 150 in conjunction with storing the data. Where the existing data is encrypted with this received encryption key before being stored, in another embodiment the token directive generation module 1002 generates an encryption erase command along with generating a token directive in response to receiving a request to overwrite the existing data. The encryption erase command erases the encryption key used to store the existing data so that the encryption key is non-recoverable.	252	Added by DJM 3 2021	3/24/21, 12:00 AM
