摘要:
A system and method are disclosed for testing operation of a memory card within an electronic host device. The system includes a flat flexible cable, or strip, for electrically coupling between the memory card slot in a host device and a test assembly. The test assembly may have a card slot for accepting an external memory card, and a debug header for receiving a cable connected to a debug apparatus such as a logic analyzer and/or an oscilloscope.

A semiconductor device is disclosed including die bond pads which are heightened to allow wire bonding of offset stacked die even in tight offset configurations. After a first die is affixed to a substrate, one or more layers of an electrical conductor may be provided on some or all of the die bond pads of the first substrate to raise the height of the bond pads. The conductive layers may for example be conductive balls deposited on the die bond pads of the first substrate using a known wire bond capillary. Thereafter, a second die may be added, and wire bonding of the first die may be accomplished using a known wire bond capillary mounting a wire bond ball on a raised surface of a first semiconductor die bond pad.

Techniques are presented for sending an application instruction from a hosting digital appliance to a portable medium, where the instruction is structured as one or more units whose size is a first size, or number of bytes. After flushing the contents of a cache, the instruction is written to the cache, where the cache is structured as logical blocks having a size that is a second size that is larger (in terms of number of bytes) than the first size. In writing the instruction (having a command part and, possibly, a data part), the start of the instruction is aligned with one of the logical block boundaries in the cache and the instruction is padded out with dummy data so that it fills an integral number of the cache blocks. When a response from a portable device to an instruction is received at a hosting digital appliance, the cache is similarly flushed prior to receiving the response. The response is then stored to align with a logical block boundary of the cache.

One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file contains a valid RO or not. Preferably, there is a one-to-one correspondence between the location for a RO in a RO file and a location in the RO navigation file for the status bit which identifies whether its corresponding location in the RO file contains a valid RO or not. Whether a particular location in a RO file contains a valid RO or not can be found by checking its corresponding status bit in the RO navigation file.
摘要:
A method of accessing content includes installing a file system filter for a secure removable memory device on a host device. A challenge is sent from the file system filter to a software entity on the host device, and a software entity response is received at the file system filter in response to the challenge. A file system filter response is calculated at the file system filter using the challenge, and access to first content on the secure removable memory device is provided if the software entity response matches the file system filter response.
摘要:
Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.

A method of accessing content includes installing a file system filter for a secure removable memory device on a host device. A challenge is sent from the file system filter to a software entity on the host device, and a software entity response is received at the file system filter in response to the challenge. A file system filter response is calculated at the file system filter using the challenge, and access to first content on the secure removable memory device is provided if the software entity response matches the file system filter response.
