Abstract
Nonvolatile memory devices including memory cell arrays with first bit line regions and common source tapping regions which are alternately disposed on a substrate along a direction, a page buffer including second bit line regions aligned with the first bit line regions and page buffer tapping regions aligned with the common source tapping regions, and a plurality of bit lines spaced apart from one another and extending to the second bit line regions from the first bit line regions.
Claims20
A nonvolatile memory device, comprising:
- a memory cell array including a plurality of first bit line regions alternating with a plurality of common source tapping regions on a substrate;
- a page buffer including a plurality of second bit line regions aligned with the first bit line regions and a plurality of page buffer tapping regions aligned with the common source tapping regions;
- and
- a plurality of bit lines spaced apart from one another and extending to the second bit line regions from the first bit line regions.
A nonvolatile memory device, comprising:
- bit line groups alternating with tapping line groups, each of the bit line groups including a plurality of memory cell strings and a plurality of bit lines connected to a page buffer, each of the tapping line groups including
- at least one common source tapping line configured to supply power to a common source line connected to the plurality of memory cell strings, and
- at least one page buffer tapping line configured to supply power to the page buffer.
A nonvolatile memory device, comprising:
- a first mesh structure including a plurality of common source regions of a common source line extending in a first direction and a plurality of common source tapping lines extending in a second direction, the common source tapping lines connected to the common source regions at cross points.
