VARYING-POLARITY READ OPERATIONS FOR POLARITY-WRITTEN MEMORY CELL

摘要

Methods, systems, and devices for varying-polarity read operations for polarity-written memory cells are described. Memory cells may be programmed to store different logic values based on applying write voltages of different polarities to the memory cells. A memory device may read the logic values based on applying read voltages to the memory cells, and the polarity of the read voltages may vary such that at least some read voltages have one polarity and at least some read voltages have another polarity. The read voltage polarity may vary randomly or according to a pattern and may be controlled by the memory device or by a host device for the memory device.
