Abstract:
1. A semiconductor device comprising: a writing word line; a reading word line; a bit line; a source line; a writing transistor, wherein a gate of the writing transistor is electrically connected to the writing word line; a reading transistor, wherein a drain of the reading transistor and a drain of the writing transistor are electrically connected to the bit line, and a source of the reading transistor is electrically connected to the source line; and a capacitor, wherein one electrode of the capacitor is electrically connected to a source of the writing transistor and a gate of the reading transistor, wherein an absolute value of a threshold voltage of the reading transistor is larger than a fluctuation range of a data potential of the bit line, and wherein the gate of the reading transistor comprises a compound containing nitrogen and at least one of indium and zinc.
