1. A memory device, comprising:
- a table with an output that is used to create a multiplication factor applied to a current to change the magnitude of the current and to compensate for temperature changes in the memory device;
wherein the output depends on an operating temperature of the memory device and a difference in the current between a highest specified operating temperature and a lowest specified operating temperature of the memory device.

Abstract
The present disclosure includes devices, methods, and systems for temperature compensation in memory devices, such as resistance variable memory, among other types of memory. One or more embodiments can include a memory device including a table with an output that is used to create a multiplication factor for a current to compensate for temperature changes in the memory device, where the output depends on an operating temperature of the memory device and a difference in the current between a highest specified operating temperature and a lowest specified operating temperature of the memory device.

13. A memory device, comprising:
-
a first group of sets of fuses, where each set of fuses has an output corresponding to a respective one of a plurality of reference currents at one of a lowest specified operating temperature and a highest specified operating temperature of the memory device; and a second group of sets of fuses, where each set of fuses of the second group has an output corresponding to a difference in magnitude between a respective one of the reference currents at the lowest specified operating temperature and at the highest specified operating temperature of the memory device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
