For the cells of the same column, the two power-switches respectively perform independent supply voltage controls for the two inverters in each cell according to data-in voltages of the bit-lines during Write operation. | 02-23-2012 |
20130222071 | Oscillator based on a 6T SRAM for measuring the Bias Temperature Instability - The present invention provides an oscillator which is based on a 6T SRAM for measuring the Bias Temperature Instability. The oscillator includes a first control unit, a first inverter, a second control unit, and a second inverter. The first control unit is coupled with the first inverter. The second control unit is coupled with the second inverter. The first control unit and the second control unit is used to control the first inverter and the second inverter being selected, biased, and connected respectively, so that the NBTI and the PBTI of the SRAM can be measured separately, and the real time stability of the SRAM can be monitored immediately. | 08-29-2013 |
20130223136 | SRAM based on 6 transistor structure including a first inverter, a second inverter, a first pass-gate transistor, and a second pass-gate transistor - The present invention provides a 6T SRAM including a first inverter, a second inverter, a first pass-gate transistor, and a second pass-gate transistor. The first inverter zs a first pull-up transistor and a first pull-down transistor. The second inverter includes a second pull-up transistor and a second pull-down transistor. The gate of the second pull-up transistor is coupled with the gate of the second pull-down transistor, and the drain of the second pull-up transistor is coupled with the drain of the second pull-down transistor. The SRAM can measure the trip voltage, the read disturb voltage, and the write margin by controlling the first bit line, the second bit line, the GND, the first word line, and the voltage source without changing of the physic parameter of the SRAM. | 08-29-2013 |
