Patent number: 10593413Abstract: A memory array comprising a word line and a bit line is disclosed. Each of a plurality of memory cells of the memory array has a first terminal connected to the bit line and a current path between the first terminal and a respective second terminal. A first memory cell of the plurality of memory cells has the second terminal coupled to receive a first supply voltage when selected by the word line. A second memory cell of the plurality of memory cells has the second terminal coupled to receive a voltage different from the first supply voltage when the first memory cell is selected by the word line.Type: GrantFiled: August 24, 2018Date of Patent: March 17, 2020Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Stephen Keith Heinrich-Barna, Raviprakash Suryanarayana Rao

Patent number: 9236096Abstract: An embodiment of the invention discloses a method for writing concurrently a binary logical value to one or more dummy memory cells in a dummy bit line pair. A diode is electrically connected between a power supply and the positive power supply line connected to the dummy memory cells. The binary logical value is then driven on to the dummy bit line pair. Next, one or more dummy word lines are driven to a logical high allowing selected dummy memory cells to be written with the binary logical value. After the selected dummy memory cells have been written to, the one or more dummy word lines are driven to a logical low. Next the diode is disabled by turning on a PFET connected between the power supply and the positive power supply line. Turning on the PFET also electrically connects the power supply to the positive power supply line.Type: GrantFiled: September 12, 2012Date of Patent: January 12, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Srinivasa Raghavan Sridhara, Raviprakash Suryanarayana Rao

Patent number: 8305814Abstract: Single-ended sense amplifier circuit. An example of the sense amplifier circuit includes an inverter coupled to a bit line to read a bit cell. The sense amplifier circuit also includes a first circuit responsive to a control signal to charge the bit line for a predefined time. Further, the sense amplifier circuit includes a second circuit coupled to the bit line and responsive to a read 1 operation to retain voltage of the bit line above a first threshold to render the inverter to read 1 from the bit cell.Type: GrantFiled: November 12, 2009Date of Patent: November 6, 2012Assignee: Texas Instruments IncorporatedInventors: Shahid Ali, Raviprakash Suryanarayana Rao
