Patent number: 9495495Abstract: One or more systems and methods for scan cell assignment for a design layout of a semiconductor arrangement are provided. The design layout is evaluated to identify a set of sequential cells, such as flip flops connected to circuitry by data paths. Sequential cells within the set of sequential cells are assigned to either a scan cell assignment or a non-scan cell assignment based upon a control path criterion, a register bank criterion, a pipeline depth criterion, a sequential loop criterion, or other criteria to create a cell assignment list. Scan paths are connected to sequential cells assigned to the scan cell assignment so that test patterns can be sent to and received from such sequential cells during testing of the semiconductor arrangement for defects. Power, performance, and area utilization are improved because at least some sequential cells are assigned to the non-scan cell assignment.Type: GrantFiled: April 3, 2014Date of Patent: November 15, 2016Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Cheng-Chung Lin, Ming-Zhang Kuo, Sang Hoo Dhong, Ho-Chieh Hsieh, Kuo Feng Tseng

Patent number: 9286970Abstract: A memory includes a word line, a bit line and a complementary bit line. A memory cell has a data node coupled to the bit line and a complementary data node coupled to the complementary bit line. The word line controls access to the memory cell. A circuit is coupled to the bit line and the complementary bit line. The circuit is configured to pull up to a high voltage, pull down to a low voltage, or float the bit line and the complementary bit line based on a first timing of pre-charging and a second timing of write driving. The first timing and the second timing are synchronized.Type: GrantFiled: July 8, 2014Date of Patent: March 15, 2016Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Ming-Zhang Kuo, Cheng-Chung Lin, Ho-Chieh Hsieh, Kuo Feng Tseng, Sang Hoo Dhong
