Abstract
Some embodiments include apparatuses and methods having a conductive line, a memory cell string including memory cells located in different levels the apparatus, and a select circuit including a select transistor and a coupling component coupled between the conductive line and the memory cell string. Other embodiments including additional apparatuses and methods are described.
Claims34
An apparatus comprising:
- a conductive line;
- a memory cell string including memory cells located in different levels of the apparatus;
- and
- a select circuit including a transistor and a coupling component coupled between the conductive line and the memory cell string.
1 more element
An apparatus comprising:
- a data line;
- a select transistor coupled to the data line;
- a memory cell string coupled to the select transistor, the memory cell string including memory cells;
- and
- a module configured to turn on the select transistor during a first time interval and a second time interval of an operation of the apparatus if one of the memory cells is selected to store information in the operation, and the module configured to turn on the select transistor during at least a portion of the first time interval and turn off the select transistor during the second time interval if no memory cells of the memory string are selected to store information in the operation.
2 more elements
An apparatus comprising:
- a data line;
- a select circuit including a coupling component coupled to the data line;
- a memory cell string coupled to the select circuit, such that the coupling component is between the data line and the memory cell string, the memory cell string including memory cells;
- and
- a module configured to turn on the coupling component if one of the memory cells is selected to store information in an operation of the apparatus, the module configured to turn on the coupling component if no memory cells of the memory cell string are selected to store information in an operation of the apparatus.
2 more elements
An apparatus comprising:
- a substrate;
- a pillar extending outwardly from the substrate;
- memory cells and associated control gates located in different levels of the apparatus and along a first portion of the pillar;
- a first select gate, a control line, and a second select gate located in different levels of the apparatus and along a second portion of the pillar;
- and
- a conductive line coupled to the pillar, wherein the first select gate, the control line, and the second select gate are between the conductive line and the memory cells.
3 more elements
A method comprising:
- turning on a select transistor coupled between a data line and a memory cell string of a device during a first time interval and a second time interval of an operation of the device if one of memory cells of the memory cell string is selected to store information in the operation;
- and
- turning on the select transistor during at least a portion of the first time interval and turning off the select transistor during the second time interval if no memory cells of the memory string are selected to store information in the operation.
