SEMICONDUCTOR STORAGE DEVICE |
| 摘要 |
A semiconductor includes a plurality of memory cell arrays each of which includes a plurality of memory cells. Bitlines extend in one direction in the memory cell arrays to transfer data stored in the memory cells. Wordlines extend perpendicular to the bitlines in the memory cell arrays to select at least one of the memory cells. Local data lines extend parallel to the wordlines outside of the memory cell arrays and convey signals from bitlines. Global data lines convey signals from the local data lines. The global data lines include a part extending parallel to the wordlines and the part is disposed over another one of the memory cell arrays other than a selected memory cell array. |

1. A semiconductor comprising:
a plurality of memory cell arrays each of which includes a plurality of memory cells; bitlines extending in one direction in the memory cell arrays to transfer data stored in the memory cells; wordlines extending perpendicular to the bitlines in the memory cell arrays to select at least one of the memory cells; local data lines which extend parallel to the wordlines outside of the memory cell arrays and which convey signals from bitlines; and global data lines which convey signals from the local data lines; wherein the global data lines include a part extending parallel to the wordlines and the part is disposed over another one of the memory cell arrays other than a selected memory cell array. |
