Methods for estimating playback time and handling a cumulative playback time permission are provided. In one embodiment, a file is streamed from a first device to a second device for playback. The amount of data of the file that was streamed to the second device is determined, and a playback time of the file is estimated using a time rate associated with the file and the determined amount of data of the file that was streamed to the second device. If the file is associated with a permission specifying an allowed cumulative playback time of the file, the estimated playback time can be accrued against the allowed cumulative playback time. Other embodiments are disclosed, and each of the embodiments described herein can be used alone or in combination with one another.

Device for estimating playback time and handling a cumulative playback time permission

A third party facilitates preparation of a backup SSD for backing up a source SSD. Digital data of the source SSD, which includes protected and sensitive data and information, is copied to the backup SSD either by and via the third party or directly from the source SSD but under supervision of the third party. The digital data of the source SSD is copied to the backup SSD under stringent rules and only if each party (i.e., the source SSD, destination SSD, and third party) proves to a counterpart device with which it operates that it is authorized to send to it digital data or to receive therefrom digital data, depending on the device with which that party operates.

Methods for estimating playback time and handling a cumulative playback time permission

A method and system is disclosed that remaps logical block addresses (LBAs) for defragmentation that is managed at the storage device level. The remapping may include sequentially remapping LBAs where individual files are remapped so that each file is referenced by sequential LBAs. The remapping of LBAs may be performed without changes to the physical location of data.

Logical block address remapping

A third party is configured to establish a virtual secure channel between a source SSD and a destination SSD via which the third party reads protected digital data from the source SSD and writes the protected digital data into the destination SSD after determining that each party satisfies eligibility prerequisites. An SSD is configured to operate as a source SSD, from which protected data can be copied to a destination SSD, and also as a destination SSD, to which protected data of a source SSD can be copied.

System and method for copying protected data from one secured storage device to another via a third party

A removable electronic circuit card having both a memory module with a non-volatile mass storage memory and a separate input-output module so that data transfers may be made through the input-output module directly to and from the mass storage memory in a direct memory access (DMA) type transfer when the card is inserted into the host system but without having to pass the data through the host system. Once the host gives a DMA command, the data transfer is accomplished independently of the host system, except for the host supplying power and possibly a clock signal and other like support, during such a data transfer directly with card. The data for the transfer can be communicated between the input-output module and the exterior device through either wireless or an electrical connection means.

Combination non-volatile memory and input-output card with direct memory access

A counting device includes a set of memory cells, which are configured to store respective bits of a count code. A controller is coupled to the memory cells so as to increment, in response to occurrences of a count input, the count code in the set of the memory cells from an initial value up to a preset bound in each of a plurality of successive iterations, and to shift the bits of the count code that are respectively stored in the memory cells in each of the iterations relative to a preceding iteration.

Counter using shift for enhanced endurance

A removable electronic circuit card has multiple modules connected to the card's bus in parallel so that each module can exchange commands and data independently with the host. According to a first aspect of the present invention, this achieved by a controller-to-controller interface whereby the modules can facilitate their interactions with the host. In a first set of embodiments, the modules are on a single card, while in a second set of embodiments the modules are distributed across multiple cards, where a first card attaches to the host and other cards attach to the first card rather than directly to the host. In all of these cases, the host sees the multiple modules as a single card having a single module. In a further aspect of the present invention, the card or cards are able to communicate with the host in more than one protocol.
