Patent number: 8826090Abstract: The present disclosure describes using the JTAG Tap's TMS and/or TCK terminals as general purpose serial Input/Output (I/O) Manchester coded communication terminals. The Tap's TMS and/or TCK terminal can be used as a serial I/O communication channel between; (1) an IC and an external controller, (2) between a first and second IC, or (3) between a first and second core circuit within an IC. The use of the TMS and/or TCK terminal as serial I/O channels, as described, does not effect the standardized operation of the JTAG Tap, since the TMS and/or TCK I/O operations occur while the Tap is placed in a non-active steady state.Type: GrantFiled: January 24, 2014Date of Patent: September 2, 2014Assignee: Texas Instruments IncorporatedInventor: Lee D.

Publication number: 20140241066Abstract: A non-volatile memory, such as a one-time programmable memory, with a dual purpose read/write cache. The read/write cache is used as a write cache during programming, and stores the data to be written for a full row of the memory array. The programming operation simultaneously programs all cells in the selected row based on the contents of the write cache. In subsequent read operations, the read/write cache is used as a read cache. A full row of the array is simultaneously read in a read access, and the contents of that row are stored in the read cache. Subsequent access to that same row causes the data to be read from the read cache rather than requiring access of the array.Type: ApplicationFiled: February 27, 2014Publication date: August 28, 2014Applicant: Texas Instruments IncorporatedInventors: David Alexander Grant, Louis A. Williams, III

Publication number: 20140240984Abstract: Apparatus and methods separate the functions of light emission, heat dissipation, and power conversion in LED lighting. Doing so may facilitate cost-effective LED lighting and enable the conversion of existing incandescent lamps to LED service. An LED light bulb includes a thermal path from LED dies to a thermal transfer contact having an externally available surface. The LED light bulb and an incandescent lamp adapter are consumer-installable in an incandescent lamp. A heat spreader component of the lamp adapter contacts the thermal transfer contact of the LED light bulb to dissipate heat originating at the LED dies. A lamp adaptable LED power supply plugs into a standard AC power outlet and includes a receptacle to accept insertion of a lamp cord plug to deliver power to the LED light bulb. A lock-in safety device prevents retraction of the lamp cord plug from the LED power supply once inserted.Type: ApplicationFiled: March 14, 2014Publication date: August 28, 2014Applicant: Texas Instruments IncorporatedInventor: James Aliberti
