20150078066 | SEMICONDUCTOR MEMORY DEVICE AND DRIVING METHOD OF SEMICONDUCTOR MEMORY DEVICE - A novel semiconductor memory device whose power consumption is low is provided. A source of a writing transistor WTr_n_m, a gate of a reading transistor RTr_n_m, and one electrode of a capacitor CS_n_m are connected to each other. A gate and a drain of the writing transistor WTr_n_m are connected to a writing word line WWL_n and a writing bit line WBL_m, respectively. The other electrode of the capacitor CS_n_m is connected to a reading word line RWL_n. A drain of the reading transistor RTr_n_m is connected to a reading bit line RBL_m. Here, the potential of the reading bit line RBL_m is input to an inverting amplifier circuit such as a flip-flop circuit FF_m to be inverted by the inverting amplifier circuit. This inverted potential is output to the writing bit line WBL_m. | 2015-03-19 |
20150078067 | METHOD OF MEASURING THRESHOLD VOLTAGE OF MOS TRANSISTOR IN SRAM ARRAY - Methods of measuring threshold voltages of MOS transistors in a SRAM array are provided. The SRAM array includes array-arranged cells having a first pass NMOS transistor, a second pass NMOS transistor, a first pull-down NMOS transistor, a second pull-down NMOS transistor, a first pull-up PMOS transistor, and a second pull-up transistor. A cell is selected from the SRAM array by a row decoding and a column decoding. A voltage is applied to a word line, a first bit line, a second bit line, a first power line, a second power line, a first substrate terminal, and/or a second substrate terminal, that are connected to the selected cell. A bit line current of the selected cell is measured to obtain a threshold voltage of a MOS transistor in the selected cell. Threshold voltages of a large number of MOS transistors in a SRAM array can be measured. | 2015-03-19 |
