Abstract: A memory array including a first region in which a first memory sub-array is located and a second region separated from the first region in which a second memory sub-array is located. The first and second memory sub-arrays have flash memory cells coupled to a plurality of word lines. A driver region separates the first and second regions and includes word line driver circuits coupled to the word lines of the first and second memory sub-arrays. A row decoder region adjacent the first region and separate from the driver region includes at least some sub-circuits of row decoder circuits located therein. The row decoder circuits are coupled to the word line driver circuits located in the driver region and are configured to activate driver circuits to drive word lines of the first and second memory sub-arrays in response to decoding address signals selecting the particular row decoder circuit.

Abstract: A computer research tool for indexing, searching and displaying data is disclosed. Specifically, a computer research tool for performing computerized research of data including textual objects in a database and for providing a user interface that significantly enhances data presentation is described. Textual objects and other data in a database are indexed by creating a numerical representation of the data. The indexing technique called proximity indexing generates a quick-reference of the relations, patterns and similarity found among the data in the database. Proximity indexing indexes the data by using statistical techniques and empirically developed algorithms. Using this proximity index, an efficient search for pools of data having a particular relation, pattern or characteristic can be effectuated. The Computer Search program, called the Computer Search Program for Data represented in Matrices (CSPDM), provides efficient computer search methods.
