Nonvolatile programmable logic switch
摘要:
An aspect of the present embodiment, there is provided a nonvolatile programmable logic switch including a first memory cell transistor, a second memory cell transistor, a pass transistor and a first substrate electrode applying a substrate voltage to the pass transistor, wherein a writing voltage is applied to the first wiring, a first voltage is applied to one of a second wiring and a third wiring and a second voltage which is lower than the first voltage is applied to the other of the second wiring and the third wiring, and the first substrate voltage which is higher than the second voltage and lower than the first voltage is applied to a well of the pass transistor, when data is written into the first memory cell transistor or the second memory cell transistor.
