Patent number: 8207451Abstract: A ground-plane slotted type signal transmission circuit board is proposed, which is designed for use with a high-speed digital signal processing system for providing a low-loss signal transmission function. The proposed circuit board structure is characterized by the formation of a slotted structure (i.e., elongated cutaway portion) in the ground plane at the beneath of each signal line. Since the slotted structure is a void portion, the electric field of a gigahertz signal being transmitting through the overlaying signal line would be unable to induce electric currents in the void portion of the ground plane. This feature allows the prevention of a leakage current that would otherwise flow from the signal line to the ground plane, and therefore can help prevent unnecessary power loss of the transmitted signal.Type: GrantFiled: September 24, 2008Date of Patent: June 26, 2012Assignee: National Taiwan UniversityInventors: Hsin-Chia Lu, Tsung-Yi Chou

Patent number: 8164958Abstract: The invention provides a method for reading a first data storage of a memory cell. The method comprises sensing a first current of the memory cell by applying a first bit line voltage on the memory cell. When the first current is larger than a first reference current with respect to the first bit line voltage, the first data storage is determined to be at an un-programmed state. Otherwise, a second current of the memory cell is sensed by applying a second bit line voltage on the memory cell. When the difference between the first current and the second current is larger than the difference between the first reference current and the second reference current, the first data storage is determined to be at the un-programmed state. Otherwise, the first data storage is determined to be at a programmed state.Type: GrantFiled: April 7, 2009Date of Patent: April 24, 2012Assignee: MACRONIX International Co., Ltd.Inventors: Tsung-Yi Chou, Loen-Shien Tsai
