  • Patent number: 11320478
    Abstract: In a method of testing a semiconductor wafer, a probe tip contacts a pad in a scribe line space between facing sides of first and second dies. The probe tip is electrically coupled to an automated test equipment (ATE). The second die is spaced apart from the first die. The scribe line space includes an interconnect extending along at least an entire length of the facing sides of the first and second dies. The pad is electrically coupled through the interconnect to at least one of the first or second dies. With the ATE, circuitry is tested in at least one of the first or second dies. The pad is electrically coupled through the interconnect to the circuitry.

  • Patent number: 10684322
    Abstract: In a method of testing a semiconductor wafer including a scribe line and multiple dies, the method includes implementing a first landing pad on the scribe line, and implementing a first interconnect on the scribe line and between the first landing pad and a first cluster of the dies, thereby coupling the first landing pad to the first cluster of dies. The method also includes performing the testing of the first cluster of dies using automated test equipment (ATE) coupled to a probe tip by contacting the first landing pad with the probe tip, and applying an ATE resource to the first cluster of dies.

  • Patent number: 9496024
    Abstract: A system on a chip (SOC) includes a processor and a memory system coupled to the processor. The memory system includes a static random access memory (SRAM) bank and a memory controller. The SRAM bank includes a first switch coupled to a SRAM array power supply and a source of a transistor of an SRAM storage cell in an SRAM array. The SRAM bank also includes a second switch coupled to a NWELL power supply and a bulk of the transistor of the SRAM storage cell. The second switch is configured to close prior to the first switch closing during power up of the SRAM array.

  • Patent number: 6771118
    Abstract: A method for reducing a leakage current in an integrated circuit is provided that includes controlling one or more inputs of an integrated circuit such that one or more logic elements within the integrated circuit are set to one or more selected values. The selected values produce a minimum leakage current associated with the integrated circuit when the integrated circuit is operating in a standby mode.
