    摘要: Memory devices and methods are disclosed, such as devices configured to store a number of access line biasing patterns to be applied during a memory device operation performed on a particular row of memory cells in the memory device. Memory devices are further configured to support modification of the stored bias patterns, providing flexibility in biasing access lines through changes to the bias patterns stored in the memory device. Methods and devices further facilitate performing memory device operations under multiple biasing conditions to evaluate and characterize the memory device by adjustment of the stored bias patterns without requiring an associated hardware change to the memory device.
