摘要:
Methods of operating a memory, and memory configured to perform similar methods, might include sensing a state of each data line of a plurality of data lines while increasing a voltage level applied to each access line of a plurality of access lines commonly connected to a plurality of strings of series-connected memory cells, ceasing increasing the voltage level applied to each access line of the plurality of access lines in response to the state of each data line of the plurality of data lines having a particular condition, changing a voltage level applied to a particular access line of the plurality of access lines to a particular voltage level, and sensing a state of each data line of a subset of the plurality of data lines while applying the particular voltage level to the particular access line.
