    摘要: A high speed/large capacity DRAM (Dynamic Random Access Memory) is generally refreshed each 0.1 sec because it loses information stored therein due to a leakage current. The DRAM also loses information stored therein upon cutoff of a power source. Meanwhile, a nonvolatile ROM (Read-only Memory) cannot be configured as a high speed/large capacity memory.
    A semiconductor memory device of the present invention realizes nonvolatile characteristic by shielding a drain functioning as a memory node from a leakage current by a tunnel insulator, and also realizes stable and high speed operation by adding a transistor for reading to a memory cell.
