Abstract
A semiconductor chip includes a memory cell array and a wiring layer. The memory cell array includes a plurality of blocks arranged in a first direction along a surface of the semiconductor chip. The wiring layer includes a plurality of first pattern regions at different positions along the first direction, each first pattern region including a different pattern corresponding to one or more of the blocks. The first pattern regions can be used to identify portions of the semiconductor chip during analysis or the like.

A semiconductor chip, comprising:
- a memory cell array including a plurality of blocks arranged in a first direction along a surface of the semiconductor chip;
- and
- a wiring layer including a plurality of first pattern regions at different positions along the first direction, each first pattern region including a different pattern corresponding to one or more of the blocks.
A semiconductor chip, comprising:
- a memory cell array including a plurality of blocks arranged in a first direction;
- and
- a plurality of wirings extending in the first direction and arranged in a second direction intersecting the first direction, wherein
- wirings in the plurality of wirings each include a plurality of pattern regions that are different at positions in the second direction, the plurality of pattern regions each including identification patterns that are different from each other.
