Semiconductor memory device
摘要:
Provided is a semiconductor memory device including an oxide semiconductor insulated gate FET and having a capability to implement advanced performance without being affected by a variation in threshold voltage. A memory cell MC includes a memory node Nm formed at a connection point of a gate of a first transistor element T1, a source of a second transistor element T2, and one end of a capacitive element Cm, and a control node Nc formed at a connection point of a drain of the first transistor element T1 and a drain of the second transistor element T2. Each memory cell MC arranged in the same column includes the control node Nc connected to a shared first control line CL extending in a column direction, the first transistor element T1 having a source connected to a shared data signal line DL extending in the column direction, the second transistor element T2 having a gate connected to an individual first selection line WL, and the capacitive element Cm having the other end connected to an individual second selection line GL, and a switching element SE having one end connected to the first control line CL, and the other end connected to a voltage supply line VL is provided with respect to each first control line CL.
