<p>PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory in which decoder part area overhead of a nonvolatile semiconductor memory provided with a plurality of banks and a page read function is suppressed and a chip cost can be reduced. SOLUTION: Data line 3 for read and data line 4 for write/verifying connected to a bit line 5 of a first nonvolatile memory bank 1 and a bit line 6 of a second nonvolatile memory bank 2 respectively and selectively are provided at a region between a first and a second nonvolatile memory banks 1, 2, and the first and the second nonvolatile memory banks 1, 2 share the data lines 3 for read and the data line 4 for write/verifying. By using such constitution, as the first nonvolatile memory bank and the second nonvolatile memory bank can share data lines, pattern occupancy area can be reduced.</p> |
