  • Patent number: 7541058
    Abstract: A circuitized substrate (e.g., PCB) including an internal optical pathway as part thereof such that the substrate is capable of transmitting and/or receiving both electrical and optical signals. The substrate includes an angular reflector on one of the cladding layers such that optical signals passing through the optical core will impinge on the angled reflecting surfaces of the angular reflector and be reflected up through an opening (including one with optically transparent material therein), e.g., to a second circuitized substrate also having at least one internal optical pathway as part thereof, to thus interconnect the two substrates optically. A method of making the substrate is also provided.

  • Publication number: 20090135885
    Abstract: This patent disclosure presents circuits, systems and methods to spread a clock signal to produce a random spreading for the clock signal that offers the maximum possible power density reduction for the spurious radiations generated from the clock signal and its harmonics. These new inventions utilize a non-linear feedback control loop to assist in generation of the spread spectrum clock and result in electronic products that can pass the FCC requirements for spurious radiations generated by the clock signal and its harmonics without utilizing expensive shielding and other EMI suppression methods.

  • Patent number: 7518270
    Abstract: A stepper motor includes a rotor having equally spaced rotor teeth defining a full step angle, and a stator with stator poles wound with coils that can be driven in a series of phases so as to magnetically interact with the rotor to produce stepping motion. The stator poles have teeth organized into two groups when there is an even number of stator teeth per pole, or into three groups for an odd number of stator teeth per pole. The stator teeth have an average pitch different from the rotor's tooth pitch, but the groups of stator teeth are also displaced relative to other groups by a specified offset angle of one-half or one-quarter step to double the number of detent positions, and to displace such detent positions from full one-phase ON or two-phase ON positions.

  • Publication number: 20090093073
    Abstract: A method of making a circuitized substrate (e.g., PCB) including at least one and possibly several internal optical pathways as part thereof such that the resulting substrate will be capable of transmitting and/or receiving both electrical and optical signals. The method involves forming at least one opening between a side of the optical core and an adjacent upstanding member such that the opening is defined by at least one angular sidewall. Light passing through the optical core material (or into the core from above) is reflected off this angular sidewall. The medium (e.g., air) within the opening thus also serves as a reflecting medium due to its own reflective index in comparison to that of the adjacent optical core material. The method utilizes many processes used in conventional PCB manufacturing, thereby keeping costs to a minimum.

  • Patent number: 7511518
    Abstract: A method of making an interposer in which at least two dielectric layers are bonded to each other to sandwich a plurality of conductors there-between. The conductors each electrically couple a respective pair of opposed electrical contacts which are formed within and protrude from openings which are also formed within the dielectric layers as part of this method. The resulting interposer is ideally suited for use as part of a test apparatus to interconnect highly dense patterns of solder ball contacts of a semiconductor chip to lesser dense arrays of contacts on the apparatus's printed circuit board.

  • Publication number: 20090070521
    Abstract: A portion of a nonvolatile memory array that is likely to contain, partially programmed data may be identified from a high sensitivity read, by applying stricter than usual ECC requirements, or using pointers to programmed sectors. The last programmed data may be treated as likely to be partially programmed data. Data in the identified portion may be copied to another location, or left where it is with an indicator to prohibit further programming to the same cells. To avoid compromising previously stored data during subsequent programming, previously stored data may be backed up. Backing up may be done selectively, for example, only for nonsequential data, or only when the previously stored data contains an earlier version of data being programmed. If a backup copy already exists, another backup copy is not created. Sequential commands are treated as a single command if received within a predetermined time period.

  • Publication number: 20090041173
    Abstract: This patent disclosure presents circuits, systems and methods to extract the clock signal from a data stream. This new invention is far better than the current technologies in the range of frequency locking and tracking. Since the new data clock recovery system is built by digital circuits only, it can be implemented inside an IC easily. This invention is especially helpful for high speed data communication products since the clock can be recovered at full data rate.

  • Patent number: 7477547
    Abstract: The quality of data stored in individual blocks of memory cells of a flash memory system is monitored by a scrub read of only a small portion of a block, performed after data are read from less than all of a block in response to a read command from a host or memory controller. The small portion is selected for the scrub read because of its greater vulnerability than other portions of the block to being disturbed as a result of the commanded partial block data read. This then determines, as the result of reading a small amount of data, whether at least some of the data in the block was disturbed by the command data read to a degree that makes it desirable to refresh the data of the block.

  • Publication number: 20090006667
    Abstract: A memory apparatus and method of operation therefore includes control by a memory controller which, in one embodiment, is configured to configure a host sector application flag table in the memory array, the flag table associating each flag value with an address in the memory array where information associated with that flag value is stored. In a second embodiment the controller is configured to (a) write at least one page of information to the memory, each page having a plurality of sectors, each of the at least one pages including a page header having a flag value associated with information written to the page, and (b) configure an exception block in memory, the exception block including exception entries, each exception entry having at least an exception flag value and address information identifying an address range in the memory array to which the exception flag value applies.

  • Publication number: 20080316815
    Abstract: A memory system includes a first block in which data is stored with a low density and a second block in which data is stored with a high density. When data is received it is written to the first block, and in parallel some of the data is written to the second block, so that the second block is partially programmed. The second block is later fully programmed by copying additional data from the first block.

  • Publication number: 20080320346
    Abstract: In a nonvolatile memory system, first raw data is obtained from stored data using a first set of reading parameters. Subsequently, the first raw data is transferred to an ECC circuit where it is decoded. While the first raw data is being transferred and decoded, second raw data is obtained from the same stored data using a second set of reading parameters.
