Abstract: The semiconductor device includes a bit line, a transistor, a retention node, and a capacitor. The transistor has a function of charging or discharging the retention node. The capacitor has a function of retaining a potential of the retention node. A voltage greater than the sum of a writing voltage and a threshold voltage is applied to a gate of the transistor. When the transistor is turned on, a first potential is supplied to the bit line with a reference potential in a floating state. A voltage less than the sum of the writing voltage and the threshold voltage is applied to the gate of the transistor. When the transistor is turned on, a second potential is supplied to the bit line with a reference potential in a floating state. With use of the first and second potentials, the threshold voltage of the transistor is calculated without being influenced by parasitic capacitance and variations in the storage capacitance of the capacitor.

Abstract: A column driver includes an amplifier circuit for amplifying data of a read bit line and a latch circuit for retaining the amplified data. The latch circuit includes a pair of nodes Q and QB for retaining complementary data. Data is read from a memory cell in each write target row to a read bit line, and amplified by the amplifier circuit. The amplified data is written to the node Q (or QB) of the latch circuit. In a write target column, write data is input to the latch circuit through the node Q (or QB) to update data of the latch circuit. Then, in each column, data of the latch circuit is written to a write bit line, and the data of the write bit line is written to the memory cell.

Abstract: To provide a semiconductor device that inhibits unexpected output of a high-level signal immediately after the rise of a power supply voltage. A semiconductor device includes a first buffer circuit, a level shifter circuit, and a second buffer circuit. A first potential is supplied to the first buffer circuit, and a second potential is supplied to the level shifter circuit and the second buffer circuit; consequently, the semiconductor device returns to a normal state. The first potential is supplied to the first buffer circuit before the second potential is supplied to the level shifter circuit and the second buffer circuit, whereby the operations of the level shifter circuit and the second buffer circuit can be controlled. This inhibits unexpected output of a high-level signal to a wiring connected to the second buffer circuit.
