Abstract: PROBLEM TO BE SOLVED: To realize isolation mechanism for a memory cell which does not occupy substrate area. SOLUTION: A memory cell array (100) contains a memory cell (10) which is arranged on an intersection point of a first conductor (30) and a second conductor (50). The memory cell (10) has a compound structure wherein data can be stored and the memory cell (10) can be isolated from a sneak path current. The memory cell (10) contains a tunnel gate surface effect transistor having uneven gate oxide (14), which is retained above columnar diode structure (12). The memory cell (10) stores a binary state in a tunnel junction (17) of gate oxide (15). Further, a control gate (63) of a transistor (62) cuts off the tunnel junction (17) from a side wall of the columnar member (12) and prevents a current from flowing. As a result, the control gate (63) prevents the sneak path current from flowing to the memory cell (10). In the isolation mechanism of the memory cell (10), a space above a substrate (40) is unnecessary, thereby enabling high-density array.
