Abstract
Methods and apparatus for programming memory cells in a memory array are disclosed. A most recent programming time is determined, the most recent programming time being a time when a most recent programming operation was applied to a reference memory cell in the memory array. A programming signal is then applied to a target memory cell in the memory array, the programming signal having a programming parameter which depends at least in part on the most recent programming time.
Claims31
A method of programming memory cells in a memory array, the method comprising:
- determining a most recent programming time, the most recent programming time being a time when a most recent programming operation was applied to a reference memory cell in the memory array;
- and
- performing a programming operation comprising applying a programming signal to a target memory cell in the memory array, the programming signal having a programming signal parameter which depends at least in part on the most recent programming time.
A memory device, the device comprising:
- a memory array comprising a plurality of memory cells;
- and
- a memory controller configured to:
- determine a most recent programming time, the most recent programming time being a time when a most recent programming operation was applied to a reference memory cell in the memory array;
- and
- perform a programming operation comprising applying a programming signal to a target memory cell in the memory array, the programming signal having a parameter which depends at least in part on the most recent programming time.
The device claim of 21, wherein the target memory cell is in the portion of the memory array.
A memory system, the system comprising:
- a memory array including a plurality of memory cells;
- a processor configured to execute instructions to program memory cells of the memory array;
- and
- a memory controller configured to:
- determine a most recent programming time, the most recent programming time being a time when a most recent programming operation was applied to a reference memory cell in the memory array;
- and
- perform a programming operation comprising applying a programming signal to a target memory cell in the memory array, the programming signal having a parameter which depends at least in part on the most recent programming time.
