Patent number: 8958237Abstract: An apparatus and method for executing a write operation in a static random access memory (SRAM) array including memory cells that are coupled to a plurality of word lines and to a plurality of bit lines are provided. A clock signal is generated to start a write operation. A pulse is generated on the plurality of word lines in response to the clock signal. An operation voltage of the SRAM array is lowered for a period of time during the write operation. The period of time is controlled and the pulse is ended using a tracking circuit. The tracking circuit includes a plurality of tracking memory cells. The plurality of tracking memory cells have a timing characteristic that emulates a timing characteristic of the SRAM array during the write operation. The tracking circuit controls the period of time and ends the pulse based on the emulated timing characteristic.Type: GrantFiled: November 13, 2013Date of Patent: February 17, 2015Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Hao-I Yang, Yi-Tzu Chen, Cheng-Jen Chang, Geng-Cing Lin, Yu-Hao Hu, Chia-Hao Hsu

Publication number: 20130301343Abstract: A threshold voltage measurement device is disclosed. The device is coupled to a 6T SRAM. The SRAM comprises two inverters each coupled to a FET. Power terminals of one inverter are in a floating state; the drain and source of the FET coupled to the inverter are short-circuited. Two voltage selectors, a resistor, an amplifier and the SRAM are connected in a negative feedback way. Different bias voltages are applied to the SRAM for measuring threshold voltages of two FETs of the other inverter and the FET coupled to the other inverter. The present invention uses a single circuit to measure the threshold voltages of the three FETs without changing the physical structure of the SRAM. Thereby is accelerated the measurement and decreased the cost of the fabrication process and measurement instruments.Type: ApplicationFiled: August 29, 2012Publication date: November 14, 2013Inventors: Ching-Te Chuang, Shyh-Jye Jou, Geng-Cing Lin, Shao-Cheng Wang, Yi-Wei Lin, Ming-Chien Tsai, Wei-Chiang Shih, Nan-Chun Lien, Kuen-Di Lee, Jyun-Kai Chu
