Abstract
A semiconductor device includes word lines disposed on a substrate and spaced apart in a first direction perpendicular to an upper surface of the substrate, a string select line disposed on the word lines, memory strings extending in the first direction on the substrate, each memory string including a first channel extending in the first direction through the word lines, and memory cells constituted by the word lines around the first channel, bit lines electrically connected to the memory strings, and a strapping line connected to the string select.
Claims1
A semiconductor device comprising:
- a plurality of word lines disposed on a substrate and spaced apart in a first direction perpendicular to an upper surface of the substrate;
- a string select line disposed on the plurality of word lines;
- a plurality of memory strings extending in the first direction on the substrate, wherein each memory string comprises:
- a first channel extending in the first direction through the plurality of word lines;
- a plurality of memory cells constituted by the plurality of word lines around the first channel;
- a second channel extending in the first direction through the string select line and not through any of the plurality of wordlines;
- and
- a string select transistor constituted by the string select line around the second channel;
- a plurality of bit lines electrically connected to the plurality of memory strings;
- and
- a strapping line connected to the string select line.
