Abstract
Memories and methods of operating memories having memory cells sharing a resistance variable material.
Claims20
A memory, comprising:
- a resistance variable material;
- a first heater under a first memory cell area of the resistance variable material;
- a second heater under a second memory cell area of the resistance variable material and spaced apart from the first heater by a first distance in a first direction;
- and
- a third heater under a third memory cell area of the resistance variable material and spaced apart from the second heater by a second distance in the first direction;
- wherein the resistance variable material is contiguous in the first direction from the first heater to the third heater;
- and
- wherein the second distance is different than the first distance.
5 more elements
A method of operating a memory, comprising:
- receiving a data word;
- remapping the data word into a plurality of bit pairs;
- and
- arranging the bit pairs such that bit pairs whose bits are both to be programmed are programmed to respective pairs of memory cells of the memory sharing a resistance variable material and separated by a first distance;
- wherein memory cells of the pairs of memory cells of the memory sharing the resistance variable material and separated by a first distance are separated from adjacent memory cells of the memory sharing the resistance variable material by a second distance greater than the first distance.
2 more elements
A memory, comprising:
- a plurality of resistive storage elements in a shared resistance variable material;
- a plurality of select devices coupled to the plurality of resistive storage elements in a one-to-one relationship;
- and
- sense circuitry coupled to the plurality of select devices.
