ABSTRACT:
A semiconductor memory device includes a n-channel type MOSFET in which a drain and a gate are connected to an external power supply and a source and a back gate are connected each other. A node is connected to the source and the back gate of the n-channel type MOSFET, and a detector for detecting an input of the external power supply based on a potential of the node.
