Abstract
Methods, systems, and devices for digit line management for a memory array are described. A memory array may include a plate that is common to a plurality of memory cells. Each memory cell associated with the common plate may be coupled with a respective digit line. One or more memory cells common to the plate may be accessed by concurrently selecting the plate and each digit line associated with the plate. Concurrent selection of all digit lines associated with the plate may be supported by shield lines between the selected digit lines. Additionally or alternatively, selection of all digit lines associated with the plate may be supported by improved sensing schemes and related amplifier configurations.
Claims20
A method, comprising:
- selecting a plate that is common to a set of memory cells, each memory cell of the set of memory cells coupled with a respective digit line of a plurality of digit lines that correspond to the plate;
- selecting two or more consecutive digit lines of the plurality of digit lines during a same duration based at least in part on selecting the plate, wherein the two or more consecutive digit lines are directly adjacent to one another;
- and
- sensing a respective charge stored by each memory cell of a subset of the set of memory cells based at least in part on selecting the two or more consecutive digit lines of the plurality of digit lines.
An apparatus, comprising:
- a memory array comprising a plurality of plate groups that are each common to a respective set of memory cells, wherein:
- each respective set of memory cells is coupled with a respective digit line of a plurality of digit lines that correspond to a plate of a plate group of the plurality of plate groups;
- and
- two or more consecutive digit lines of the plurality of digit lines that correspond to the plate of the plate group are configured to be selected during a same duration, wherein the two or more consecutive digit lines are directly adjacent to one another.
An apparatus, comprising:
- a set of memory cells;
- a plate that is common to the set of memory cells;
- a plurality of digit lines that correspond to the plate and are coupled with respective memory cells of the set of memory cells;
- and
- a controller coupled with one or more of the set of memory cells, the plate, and the plurality of digit lines, wherein the controller is configured to cause the apparatus to:
- select the plate that is common to the set of memory cells;
- select two or more consecutive digit lines of the plurality of digit lines during a same duration based at least in part on selecting the plate, wherein the two or more consecutive digit lines are directly adjacent to one another;
- and
- sense a respective charge stored by each memory cell of a subset of the set of memory cells based at least in part on selecting the two or more consecutive digit lines of the plurality of digit lines.
