Abstract
The present disclosure includes memory devices and methods of operating the same. One such device includes an array of groups of memory cells, a group selector configured to select a particular group of memory cells from within the array, and a cell selector configured to select a particular memory cell from within the selected particular group of memory cells.
Claims25
A device, comprising:
- an array of groups of memory cells;
- a group selector configured to select a particular group of memory cells from within the array;
- and
- a cell selector configured to select a particular memory cell from within the selected particular group of memory cells.
1 more element
A device, comprising:
- a three-terminal group selector to select a group of memory cells from within an array of memory cells, the three-terminal group selector comprising:
- a first terminal coupled to a first conductive line;
- a second terminal coupled to a second conductive line;
- a third terminal is coupled to the group of memory cells;
- and
- a cell selector to select a memory cell from within the group of memory cells.
3 more elements
A device, comprising:
- an array of groups of memory cells, wherein each group of memory cells comprises a stack of resistance variable materials;
- a number of three-terminal group selectors configured to select particular groups of memory cells from within the array,
- wherein at least a first memory cell in a first group of the array of groups of memory cells and a second cell in a second group of the array of groups of memory cells share a source line within the array;
- and
- a number of two-terminal select devices configured to select a particular memory cell from within the selected particular group of memory cells.
2 more elements
An array of memory cells, comprising:
- a first group of memory cells selectable by a first group selector;
- a memory cell within the first group of memory cells selectable by a first cell selector;
- a second group of memory cells selectable by a second group selector and adjacent to the first group of memory cells;
- a memory cell within the second group of memory cells selectable by a second cell selector;
- wherein the memory cell within the first group of memory cells and the memory cell within the second group of memory cells share a source line of the array of memory cells.
2 more elements
A method for operating a device, comprising:
- applying a first bias to a group selector in an array of memory cells to activate the group selector;
- selecting a first group of memory cells from within the array of memory cells using the group selector;
- and
- applying a second bias between a data line and a source line in the array of memory cells to select a particular memory cell from within the selected first group of memory cells.
