Patent number: 10847236Abstract: A memory cell includes a first anti-fuse element, a first select transistor, a second anti-fuse element, a second select transistor, and a sensing control circuit. The first anti-fuse element is coupled to an anti-fuse control line, and the first select transistor transmits a voltage between a first bit line and the first anti-fuse element according to a voltage on the word line. The second anti-fuse element is coupled to the anti-fuse control line. The second select transistor transmits a voltage between a second bit line and the second anti-fuse element according to the voltage on the word line. The sensing control circuit provides a discharging path to a system voltage terminal from the first select transistor or the second select transistor according to states of the first anti-fuse element and the second anti-fuse element during a read operation.Type: GrantFiled: August 29, 2019Date of Patent: November 24, 2020Assignee: eMemory Technology Inc.Inventor: Dung Le Tan Hoang

Patent number: 10692546Abstract: A memory circuit includes a memory cell, a first program driver, a second program driver, and a sensing amplifier. A method for operating the memory circuit includes, during a program operation of the memory cell, providing a program voltage to the memory cell, enabling the first program driver to drive the first local bit line to be at a low voltage, enabling the second program driver, disabling the first program driver, and enabling the sensing amplifier to verify whether the first memory cell has been programmed or not. The second program driver has a weaker driving ability than the first program driver.Type: GrantFiled: February 26, 2019Date of Patent: June 23, 2020Assignee: eMemory Technology Inc.Inventor: Dung Le Tan Hoang

Patent number: 10650868Abstract: A sensing amplification circuit includes a sensing amplifier and a trigger control circuit. The sensing amplifier receives a data voltage and a reference voltage, and outputs a first data signal and a second data signal by comparing the data voltage and the reference voltage. The trigger control circuit includes a logic circuit and a set-reset latch. The logic circuit receives the first data signal and the second data signal, and changes a first control signal from a first voltage level to a second voltage level when one of the first data signal and the second data signal changes its state. The first set-reset latch receives the first control signal and a second control signal, and generates a trigger signal to enable the sensing amplifier when the second control signal changes state and disable the sensing amplifier when the first control signal changes state.Type: GrantFiled: February 21, 2019Date of Patent: May 12, 2020Assignee: eMemory Technology Inc.Inventors: Dung Le Tan Hoang, Hao-Chun Hu, Po-Hao Huang

Patent number: 4494899Abstract: A pipe trough for transporting pipe between upper and lower positions. A pipe carrier having a V-shaped cross-section is received within an elongate trough body having a V-shaped cross-section. The pipe carrier is longitudinally slidable along the trough and is constructed to receive one end of a pipe. A roller is mounted at one end of the trough body for supporting the other end of a pipe received within the carrier. A hydraulic motor is provided for selectively moving the carrier along the length of the trough body. Openings formed crosswise of the trough are distributed along its length. Each opening includes a pipe unloading arm having a pivotal connection to the trough at one side. A ram positioned beneath the arm and having one end pivotally attached to the arm and the other end pivotally attached to the trough is provided for raising and lowering the arm to unload the pipe from the trough.Type: GrantFiled: April 28, 1982Date of Patent: January 22, 1985Assignee: Tri-Star Enterprises, Inc.Inventors: Tan Hoang, James B.
