Abstract
Some embodiments include an apparatus having data lines coupled to memory cell strings and a selector configured to selectively couple one of the data lines to a node. The memory cell strings and the selector can be formed in the same memory array of the apparatus. Other embodiments including additional apparatus and methods are described.
Claims20
An apparatus comprising:
- a substrate;
- a data line over the substrate;
- a memory cell string including a first body region having a length between the substrate and the data line;
- and
- a selector including a second body region having a length between the substrate and the data line, the selector configured to perform at least one of coupling the data line to a node and coupling the data line to different voltages in different memory operations.
2 more elements
An apparatus comprising:
- a substrate located on a first device level;
- data lines located on a second device level;
- a memory array including a first portion and a second portion, each of the first and second portion located between the first and second device levels, the first portion including memory cell strings coupled to the data lines, the second portion including switching circuits configured to selectively couple the data lines to a node;
- and
- a sense circuit configured to determine a value of information stored in at least one of the memory cell strings based on a signal at the node.
