An insulated gate type transistor includes a plurality of major electrode regions, a channel region provided between the plurality of major electrode regions, a gate electrode provided on the channel region with a gate insulating film therebetween, and a semiconductor region provided in contact with the channel region, the semiconductor region having the same conductivity type as that of the channel region and a higher impurity concentration than the channel region. The gate electrode has at least two opposing portions. The plurality of major electrode regions are provided on an substrate insulating film. The transistor is activated in a state where the semiconductor region is maintained at a predetermined voltage. A semiconductor device includes a plurality of memory cells, each of which includes the aforementioned insulated gate type transistor and an electrically breakable memory element provided on one of the major electrode regions.
