Nonvolatile Latch Circuit And Logic Circuit, And Semiconductor Device Using The Same |
摘要 |
To provide a novel nonvolatile latch circuit and a semiconductor device using the nonvolatile latch circuit, a nonvolatile latch circuit includes a latch portion having a loop structure where an output of a first element is electrically connected to an input of a second element, and an output of the second element is electrically connected to an input of the first element; and a data holding portion configured to hold data of the latch portion. In the data holding portion, a transistor using an oxide semiconductor as a semiconductor material for forming a channel formation region is used as a switching element. In addition, a capacitor electrically connected to a source electrode or a drain electrode of the transistor is included. |
