  • Patent number: 7307267
    Abstract: The electric device (1, 100) has a body (2, 102) having a resistor (7, 107) comprising a phase change material being changeable between a first phase and a second phase. The resistor (7, 107) has a first electrical resistance when the phase change material is in the first phase and a second electrical resistance, different from the first electrical resistance, when the phase change material is in the second phase. The body (2, 102) further has a heating element (6, 106) being able to conduct a current for enabling a transition from the first phase to the second phase. The heating element (6, 106) is arranged in parallel with the resistor (7, 107).

  • Patent number: 7308625
    Abstract: A testing approach involves selective application of clock signals to target circuitry. In an example embodiment (300), a target circuit (332) having logic circuitry that processes data in response to an operational clock signal (308) having at least one clock period, is analyzed for delay faults. Test signals are applied to the logic circuitry while the logic circuitry is clocked with a high-speed test clock (309) having several clock-state transitions that occur during at least one clock period of the operational clock (308). An output from the logic circuitry is analyzed for its state (e.g., as affected by delay in the circuitry). Delay faults are detected as a difference in state of the output of the logic circuitry. With this approach, circuits are tested using conventional testers (340) that operate at normal (e.g., slow) speeds while selectively clocking selected portions of the circuit at higher speeds for detecting speed-related faults therein.

  • Patent number: 7305543
    Abstract: All pointer-based accesses require first that the value contained in a pointer register to be read and then that value be used as an address to the appropriate region in random access memory (RAM). As implemented today, this requires two memory read access cycles, each of which takes at least one clock cycle and therefore this implementation does not allow single cycle operation. In accordance with an embodiment of the invention, when an access is performed to pointer memory to read the contents of a pointer, it is the shadow memory that is actually read and that returns the pointer value. Since the shadow memory is made up of pointer registers, a read access involves multiplexing out of appropriate data for the pointer address from these pointer registers to form a target pointer address.

  • Patent number: 7298197
    Abstract: An increasing number of phases in multiphase converters causes an increase in requirements with respect to the control IC. According to the present invention, instead of deriving a new PWM signal for every single phase of the DC-DC converter, the single phases are clustered into groups (22, 24, 26). Within each group, the converters are operated on the basis of one PWM signal (PW M1, PW M2 . . . PW MN). Advantageously, this may allow to reduce the requirements with respect to the control IC and thus may allow the application of cheaper and smaller control ICs.

  • Patent number: 7288834
    Abstract: The semiconductor device has a security coating with embedded magnetic particles and magnetoresistive sensors. This renders possible a measurement of the impedance of security elements defined by magnetoresistive sensors and security coating. If initial values of the impedance are stored, actual values can be compared therewith to see if the device has not been electrically probed or modified. Such a comparison can be used to check the authenticity of the device.

  • Patent number: 7290119
    Abstract: A memory accelerator module buffers program instructions and/or data for high speed access using a deterministic access protocol. The program memory is logically partitioned into ‘stripes’, or ‘cyclically sequential’ partitions, and the memory accelerator module includes a latch that is associated with each partition. When a particular partition is accessed, it is loaded into its corresponding latch, and the instructions in the next sequential partition are automatically pre-fetched into their corresponding latch. In this manner, the performance of a sequential-access process will have a known response, because the pre-fetched instructions from the next partition will be in the latch when the program sequences to these instructions. Previously accessed blocks remain in their corresponding latches until the pre-fetch process ‘cycles around’ and overwrites the contents of each sequentially-accessed latch.
