Abstract
Methods, systems, and devices for preventing disturb of untargeted memory cells during repeated access operations of target memory cells are described for a non-volatile memory array. Multiple memory cells may be in electronic communication with a common conductive line, and each memory cell may have an electrically non-linear selection component. Following an access operation (e.g., a read or write operation) of a target memory cell, untargeted memory cells may be discharged by applying a discharge voltage to the common conductive line. The discharge voltage may, for example, have a polarity opposite to the access voltage. In other examples, a delay may be instituted between access attempts in order to discharge the untargeted memory cells.
