    • It is an object of the present invention to provide a nonvolatile memory device, in which additional writing is possible other than in manufacturing and forgery and the like due to rewriting can be prevented, and a semiconductor device having the memory device. It is another object of the present invention to provide an inexpensive and nonvolatile memory device with high reliability and a semiconductor device. According to one feature of the present invention, a memory device includes a first conductive layer formed over an insulating surface, a second conductive layer, a first insulating layer interposed between the first conductive layer and the second conductive layer, and a second insulating layer which covers a part of the first conductive layer, wherein the first insulating layer covers an edge portion of the first conductive layer, the insulating surface, and the second insulating layer.
    • 本发明的一个目的是提供一种非易失性存储器件,其中可以除了制造和伪造等以外的其他写入可能被改写,以及具有存储器件的半导体器件。 本发明的另一个目的是提供一种具有高可靠性的廉价且非易失性的存储器件和半导体器件。 根据本发明的一个特征,一种存储器件包括:在绝缘表面上形成的第一导电层,第二导电层,介于第一导电层和第二导电层之间的第一绝缘层;以及第二绝缘层, 覆盖第一导电层的一部分,其中第一绝缘层覆盖第一导电层,绝缘表面和第二绝缘层的边缘部分。
