Abstract: Portable smartcard devices, methods of operating smartcard devices, systems including a smartcard device and a terminal, and computer readable storage media including instructions for smartcard devices are provided. According to some embodiments, the smartcard includes a controller for executing commands received from a terminal, where execution of at least one command affects a power consumption of the smartcard device during subsequent execution of at least one other command. Optionally, the command which modifies smartcard power consumption is issued by the terminal in accordance with a power consumption decision.

Abstract: Portable smartcard devices, methods of executing program code using smartcard devices, and computer readable storage media including instructions for smartcard devices are provided. According to some embodiments, the presently disclosed smartcard device includes an interface for presenting smartcard functionality to a host system and for receiving a program execution command from the host system, non-volatile memory, executable memory, a copying mechanism such as an internal copying mechanism for copying program code from the non-volatile memory to the executable memory, and a program execution mechanism for executing the program code. Appropriate interfaces include but are not limited to ISO 7816 compatible interfaces, USB interfaces, and MMC interfaces. In some embodiments, the smartcard functionality includes SIM functionality and/or USIM functionality. Optionally, execution of the program code commences when only a portion of the copied executable code resides in the executable memory.

Abstract: An ASIC for implementing digital rights management includes a processor for requesting encrypted digital data from a server and decrypting the data, and a player for transforming the decrypted data to analog signals. Preferably, the ASIC is tamper-resistant. Preferably, all the management code of the ASIC is stored on a ROM in the ASIC. A device for receiving, decrypting and displaying encrypted digital data includes the ASIC, and also a transceiver for communicating with the server, a display mechanism for displaying the analog signals, and a nonvolatile memory for storing the encrypted data. A system for storing and displaying digital data includes both the server and the device. Preferably, the server is configured to send to the device only the encrypted digital data and associated decryption keys.

Abstract: Non-volatile memory devices, systems, methods and computer readable code for configuring at least a portion of a non-volatile memory to provide a requested effective endurance are disclosed. According to some embodiments, a determined amount of physical memory is allocated for the at least a portion of non-volatile memory. According to some embodiments, for a given amount of configured physical memory, requesting a greater effective endurance provides a smaller amount of logically addressable memory. According to some embodiments, for a given amount of logically addressable memory, requesting a greater effective endurance configures a greater amount of physical memory. In some embodiments, a controller is operative to configure the at least a portion of non-volatile memory. Alternatively or additionally, driver code resides on a host device coupled to the non-volatile memory device. Optionally, a value of the requested endurance is specified in a command issued to the non-volatile memory device.

Optionally, the command which modifies smartcard power consumption is issued by the terminal in accordance with a power consumption decision. According to some embodiments, as an allowed power consumption of the smartcard device increases, the performance of the smartcard increases, and vice versa.
