A semiconductor device includes a semiconductor feature, a low-k dielectric feature that is formed on the semiconductor feature, and a Si-containing layer that contains elements of silicon and that covers over the low-k dielectric feature. The Si-containing layer can prevent the low-k dielectric feature from being damaged in etch and/or annealing processes for manufacturing the semiconductor device.

Disclosed is a semiconductor device having a memory cell which comprises a transistor having a control gate and a storage gate. The storage gate comprises an oxide semiconductor and is able to be a conductor and an insulator depending on the potential of the storage gate and the potential of the control gate. Data is written by setting the potential of the control gate to allow the storage gate to be a conductor, supplying a potential of data to be stored to the storage gate, and setting the potential of the control gate to allow the storage gate to be an insulator. Data is read by supplying a potential for reading to a read signal line connected to one of a source and a drain of the transistor and detecting the change in potential of a bit line connected to the other of the source and the drain.
