Abstract
Methods of operating a memory, and apparatus configured to perform similar methods, include determining a voltage level of a stepped sense operation that activates a memory cell of the memory during a programming operation for the memory cell, and determining a voltage level of a ramped sense operation that activates the memory cell during a read operation for the memory cell.
Claims20
A method of operating a memory, comprising:
- determining a voltage level of a stepped sense operation that activates a memory cell of the memory during a programming operation for the memory cell;
- and
- determining a voltage level of a ramped sense operation that activates the memory cell during a read operation for the memory cell.
An apparatus, comprising:
- an array of memory cells;
- a controller configured to access the array of memory cells;
- wherein the controller is further configured to:
- determine a voltage level of a stepped sense operation that activates a memory cell of the array of memory cells during a programming operation for the memory cell;
- and
- determine a voltage level of a ramped sense operation that activates the memory cell during a read operation for the memory cell.
3 more elements
An apparatus, comprising:
- an array of memory cells;
- a plurality of data lines, each data line of the plurality of data lines selectively connected to a respective plurality of memory cells of the array of memory cells;
- a stepped sense circuit connected to a particular data line of the plurality of data lines;
- a ramped sense circuit connected to the particular data line;
- and
- a controller configured to access the array of memory cells;
- wherein the controller is further configured to:
- perform a programming operation using the stepped sense circuit to verify completion of the programming operation;
- and
- perform a read operation using the ramped sense circuit.
