1. A method of analyzing data, comprising: writing a plurality of data sets selected by a host in a memory array of a NAND architecture of NAND strings formed along bit lines and spanned by word lines, where the data sets are written oriented along the bit lines with corresponding data elements arranged to lie along the same word lines; concurrently biasing a plurality of word lines to a first set of sensing voltage levels corresponding to host determined parameter values; and determining those of the bit lines that conduct in response to said biasing of a plurality of word lines to the first set of sensing voltage levels.
