摘要： Methods of operating a memory device include comparing input data to data stored in memory cells coupled to a data line, comparing a representation of a level of current in the data line to a reference, and determining that the input data potentially matches the data stored in the memory cells when the representation of the level of current in the data line is less than the reference. Methods of operating a memory device further include comparing input data to first data and to second data stored in memory cells coupled to a first data line or to a second data line, respectively, comparing representations of the levels of current in the first data line and in the second data line to a first reference and to a different second reference, and deeming one to be a closer match to the input data in response to results of the comparisons.

摘要： Methods of operating memory include generating a data value indicative of a level of a property sensed from a data line while applying potentials to control gates of memory cells of more than one string of series-connected memory cells connected to that data line. Methods of operating memory further include generating data values indicative of levels of a property sensed from data lines while applying potentials to control gates of memory cells of strings of series-connected memory cells connected to those data lines, performing a logical operation on a set of data values comprising those data values, and determining a potential to be applied to control gates of different memory cells of those strings of series-connected memory cells in response to an output of the logical operation on the set of data values.
