Abstract
Methods, systems, and devices for programmable chalcogenide capacitors are described. A first programming pulse may be applied, for a first duration, to a capacitor comprising a chalcogenide material to adjust a capacitance of the capacitor from a first capacitance to a second capacitance. A pulse may be applied to the capacitor based on applying the first programming pulse to the capacitor. A first voltage may be stored in the capacitor based on adjusting the capacitance of the capacitor from the first capacitance to the second capacitance, and the first voltage may be stored based on the capacitor having the second capacitance.
Claims25
A method, comprising:
- applying, for a first duration, a first programming pulse to a capacitor comprising a chalcogenide material to adjust a capacitance of the capacitor from a first capacitance to a second capacitance;
- and
- storing a first voltage to the capacitor based at least in part on adjusting the capacitance of the capacitor from the first capacitance to the second capacitance, wherein the first voltage is based at least in part on the capacitor having the second capacitance.
An apparatus, comprising:
- a first access line;
- a second access line;
- a capacitor comprising an anode coupled with the first access line, a cathode coupled with the second access line, and a chalcogenide material;
- and
- a controller operable to cause the apparatus to:
- apply, for a first duration, a first programming pulse to the capacitor to adjust a capacitance of the capacitor from a first capacitance to a second capacitance;
- and
- store a first voltage to the capacitor based at least in part on adjusting the capacitance of the capacitor from the first capacitance to the second capacitance, wherein the first voltage is based at least in part on the capacitor having the second capacitance.
A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor to:
- apply, for a first duration, a first programming pulse to a capacitor comprising a chalcogenide material to adjust a capacitance of the capacitor from a first capacitance to a second capacitance;
- and
- store a first voltage to the capacitor based at least in part on adjusting the capacitance of the capacitor from the first capacitance to the second capacitance, wherein the first voltage is based at least in part on the capacitor having the second capacitance.
