摘要:
A nonvolatile semiconductor memory apparatus (10) of the present invention comprises a semiconductor substrate (11), an active element forming region provided on the semiconductor substrate (11) and including a plurality of active elements (12), a wire forming region which is provided on the active element forming region to electrically connect the active elements (12) and includes plural layers of semiconductor electrode wires (15, 16), a memory portion forming region (100) which is provided above the wire forming region and provided with memory portions (26) arranged in matrix, a resistance value of each of the memory portions changing according to electric pulses applied, and an oxygen barrier layer (17) which is provided between the memory portion forming region (100) and the wire forming region so as to extend continuously over at least an entire of the memory portion forming region (100).
