Systems and methods of finalizing a semiconductor memory are disclosed. A method includes receiving an instruction to finalize data at a data storage device that includes a controller coupled to a semiconductor memory. The data storage device also includes a status indicator to indicate a finalize status of the semiconductor memory. In response to receiving the instruction to finalize the data at the data storage device, the status indicator is set to a finalize value. Write to the semiconductor memory operations are prevented by the controller in response to the status indicator having the finalize value.

Methods for enabling software from a storage-capable device including the steps of: loading, by a host system operationally connected to the storage-capable device, software from an authenticatable storage area residing in the storage-capable device; validating the software; and installing the validated software, wherein the validated software provides an interface between the host system and the storage-capable device. In some embodiments, the software is enabling software, the method further including the step of loading, by the host system, device-functionality software from the authenticatable storage area. In some embodiments, the method further includes the steps of: validating the device-functionality software; and enabling the validated device-functionality software. In some embodiments, the method further includes the steps of prior to the step of loading the software, executing a probe command in the host system; and returning, by the probe command, a list of device functional units residing in the storage-capable device.

Systems and methods responsive to a data file deletion instruction are disclosed. A method includes receiving an instruction to delete a data file. The data file is stored at a plurality of persistent memory cells of a memory. The memory also stores a directory that includes a first entry corresponding to the data file. In response to receiving the instruction to delete the data file, multiple attribute bits of the first entry are programmed and also a first bit of the first entry is programmed. The first bit of the first entry is distinct from the multiple attribute bits. Programming the multiple attribute bits converts the first entry from a first entry type to a second entry type. Programming the first bit of the first entry indicates that the first entry has an unused status.

Enhanced configuration of security and access control for data in a storage device is disclosed. A request is received to access an addressable memory location in a storage media within the storage device. A set of addressable memory locations with contiguous addresses identified by an address range is associated with first and second characteristics. The first characteristic is applied if the addressable memory location is within the set of addressable memory locations, and an entity is currently authenticated to and authorized to access the set of addressable memory locations. The second characteristic is applied if the addressable memory location is within the set of addressable memory locations, and no entity is currently authenticated to and authorized to access the set of addressable memory locations. The set of addressable memory locations can also be a logical partition, where the first and second characteristics are stored in a logical partition table.

Managing access to an address range in a storage device

A storage device comprising a non-volatile memory for storing data, and an input device that is operative to select an operating mode of the storage device prior to mounting the storage device, such that each operating mode represents a different type of storage device. A controller interfaces with the input device to establish the selected operating mode of the storage device once the storage device is mounted.

Storage device for mounting to a host

A method includes defining a host capability; creating for a storage device a second directory tree from a first directory tree of the storage device that is included in a file system within the storage device; and, for a data file that is stored in the storage device and is selectable for consumption by a host through the first directory tree that is included in the storage device's file system, determining whether the data file requires for consumption a host having the defined host capability. If the data file requires a host having the defined host capability, an entry is created in the second directory tree in which the data file is not selectable for consumption by the host. Otherwise, an entry is created in the second directory tree in which the data file is selectable for consumption by the host.

Storage device presenting to hosts only files compatible with a defined host capability

Displaying storage device-generated menus for playback includes connecting a storage device to a host capable of playing back video content, and presenting to the host a root directory through which a content selection file allows selecting video files for playback through user-storage device interaction, and, optionally, one or more service files that provide various useful information that are also playable back through user-storage device interaction. This typically further includes displaying a Main Menu that represents these files and playing Main Menu items as regular video files/contents. While the content selection file is played back, a content selection menu is generated by the storage device and displayed by the host, and each content selection menu item is playable by transmitting a playback command to the storage device rather than to the host. A storage device is also provided, which uses such method.

Storage device managing playable content

A data storage device includes a non-volatile memory array, a user input device, and a host interface adapted to connect the data storage device to a host device and convey data to the host device. In response to a first operation of the user input device, application configuration data is communicated from the data storage device to the host device. The application configuration data is configured to trigger execution by the host device of a configuration application that includes a listing of a plurality of applications for display by the host device allowing a user to identify a selected application. In response to selection of an application, application designation data is generated and stored in the non-volatile memory array. In response to a second operation of the user input device, the application designation data is communicated to the host device to trigger automatic execution by the host device of the selected application.

Methods for enabling software from a storage-capable device including the steps of: loading, by a host system operationally connected to the storage-capable device, software from an authenticatable storage area residing in the storage-capable device; validating the software; and installing the validated software, wherein the validated software provides an interface between the host system and the storage-capable device. In some embodiments, the software is enabling software, the method further including the step of: loading, by the host system, device-functionality software from the authenticatable storage area. In some embodiments, the method further includes the steps of: validating the device-functionality software; and enabling the validated device-functionality software. In some embodiments, the method further includes the steps of: prior to the step of loading the software, executing a probe command in the host system; and returning, by the probe command, a list of device functional units residing in the storage-capable device.

A host device includes a first file system, and a storage device includes a plurality of memory units and a plurality of controllers. While the host device is operative coupled to the storage device, the host device creates a second file system corresponding to the storage device and copies host content from the first file system to the second file system. The second file system is segmented into a plurality of segments, each of the plurality of segments being uniquely associated with a particular one of the plurality of controllers. The host device selects a data transfer rate to write the host content from the second file system to the storage device.

The deleted data store may be either separate from the secondary data store or implemented within the secondary data store. The data management application may automatically free up space for backup of data newly added to or deleted from the primary data store, by selectively removing data from the deleted data store, based application of appropriate criteria.
