Patent number: 10607662Abstract: A Static Random Access Memory (SRAM) array power supply circuit is presented. The circuit comprises an SRAM test unit having a substantially same structure as a basic SRAM unit in the SRAM array; a switch device connected to a power source, the SRAM test unit, and the SRAM array; and a switch control circuit connected to the SRAM test unit and the switch device. When a test voltage in the SRAM test unit is lower than a threshold voltage, the switch device is closed so that the power source begins to charge the SRAM array and the SRAM test unit. The SRAM test unit provides an early warning for the SRAM array, allowing the latter to be charged upon fulfillment of a condition (e.g., charge is low). Compared to conventional circuits, this circuit provides an output voltage that is more stable and less susceptible to the changes in external conditions such as temperature or pressure.Type: GrantFiled: July 27, 2018Date of Patent: March 31, 2020Assignees: SEMICONDUCTOR MANUFACTURING INTERNATIONAL (SHANGHAI) CORPORATION, SEMICONDUCTOR MANUFACTURING INTERNATIONAL (BEIJING) CORPORATIONInventors: Chen-Yi Huang, Chia Chi Yang, Dong Xiang Luo, Cheng-Tai Huang

Publication number: 20190339328Abstract: A software-defined linear feedback shift register (SLFSR) implements a low-power test compression for launch-on-capture (LOC). Each bit of an extra register controls a stage of the SLFSR. A control vector is shifted into the extra register to indicate whether a primitive polynomial contains the stage of the non-zero bit. Therefore, SLFSR can configure any primitive polynomials with different degrees by loading different control vectors without any hardware overhead. A low-power test compression method and design for testability (DFT) architecture provide LOC transition fault testing by using seed encoding scheme, low-power test application procedure and a software-defined linear-feedback shift-register (SLFSR) architecture. The seed encoding scheme generates seeds for all test pairs by selecting a primitive polynomial that encodes all test pairs of a compact test set.Type: ApplicationFiled: March 12, 2019Publication date: November 7, 2019Inventor: Dong Xiang

Publication number: 20190018910Abstract: A new low-power test compression method and design for testability (DFT) architecture are proposed for deterministic test pairs for launch-on-capture (LOC) transition fault testing by using a new seed encoding scheme, a new low-power test application procedure and a new test compression architecture. The new seed encoding scheme generates seeds for all test pairs by selecting a primitive polynomial that encodes all test pairs of a compact test set. The low-power test compression architecture includes: (1) the LFSR established by the selected primitive polynomial and the selected number of extra variables injected to the LFSR; (2) the scan tree architecture for LOC transition fault testing; and (3) the new gating technique. A new static test compaction scheme is proposed by bitwise modifying the values of a seed and the extra variables. A new technique for test point insertion is proposed for LOC delay testing in the two-frame-circuit model, which apparently reduces test data volume.Type: ApplicationFiled: May 7, 2018Publication date: January 17, 2019Inventor: Dong XIANG

Patent number: 10084270Abstract: An electrical receptacle connector includes a metallic shell and one or more insertion modules. The metallic shell includes two first walls, two second walls, and several protrusions. The walls form an insertion space. The protrusions are extending toward the insertion space from the first walls, and the protrusions are integrally formed on the first walls seamlessly. The insertion module includes an insulated housing, first receptacle terminals, second receptacle terminals, and a grounding plate between the first receptacle terminals and the second receptacle terminals. When the electrical receptacle connector is mated with an electrical plug connector, the protrusions are in contact with a metallic shell of the electrical plug connector. Because the walls of the metallic shell are seamless, the connector assembly of the plug and receptacle can be waterproof.Type: GrantFiled: September 22, 2016Date of Patent: September 25, 2018Assignee: ADVANCED-CONNECTEK INC.Inventors: Yu-Lun Tsai, Pin-Yuan Hou, Chung-Fu Liao, Long-Fei Chen, Dong Xiang
