  • Publication number: 20180073933
    Abstract: In certain aspects, a method for temperature monitoring comprises receiving temperature readings from a plurality of temperature sensors on a chip, and determining an average or a sum of the temperature readings from the temperature sensors. The sum may be a weighted sum of the temperature readings. The method also comprises computing a temperature at a location on the chip based on the average or sum of the temperature readings. The location may be located at approximately a centroid of the locations of the temperature sensors, an estimated hotspot location on the chip, or another location on the chip.

  • Patent number: 9343127
    Abstract: A memory device comprises a memory array, at least one row address buffer, a set of row data buffers, a row decoder, an array of sense amplifiers, and a demultiplexer. The memory array comprises data elements organized into rows and columns. Each of the rows is addressable by a row address. Each of the data elements in each of the rows is addressable by a column address. The at least one row address buffer holds a selected row address of a set of successive selected row addresses. The set of row data buffers holds respective contents of selected rows that correspond to the set of successive selected row addresses. The row decoder decodes the selected row address to access a selected row. The array of sense amplifier reads the selected row and transmits content of the selected row to one of the row data buffers through the demultiplexer, and writes the content of the selected row back to the selected row.

  • Publication number: 20130285696
    Abstract: An on-chip sensor measures dynamic power supply noise, such as voltage droop, on a semiconductor chip. In-situ logic is employed, which is sensitive to noise present on the power supply of functional logic of the chip. Exemplary functional logic includes a microprocessor, adder, and/or other functional logic of the chip. The in-situ logic performs some operation, and the amount of time required for performing that operation (i.e., the operational delay) is sensitive to noise present on the power supply. Thus, by evaluating the operational delay of the in-situ logic, the amount of noise present on the power supply can be measured.

  • Patent number: 7961502
    Abstract: Electronic circuits use latches including a magnetic tunnel junction (MTJ) structure and logic circuitry arranged to produce a selective state in the MTJ structure. Because the selective state is maintained magnetically, the state of the latch or electronic circuit can be maintained even while power is removed from the electronic device.

  • Patent number: 7543207
    Abstract: A full-scan latch is provided that may be used to incorporate design for test functionality in an integrated circuit. The full-scan latch includes a shadow latch, a multiplexer, and a slave latch. The full-scan latch has a test mode and a normal mode. When in the normal mode, the device operates as a transparent latch, passing a data input to its output. When in test mode, the device is operable to pass scan data down a scan chain and to inject scan data into the data path.
