Abstract (en)

[origin: WO0201570A1] A memory system and method that enables locating memory cells that contain a searched data using a limited number of lines and thus reducing the necessary memory surface while at the same time accelerating the search process by limiting the search to cells having a predefined characteristic. The memory system comprises an address bus and a data bus, a row selector and a column selector and a two dimensional array of memory cells, each memory cell comprising a masking circuit, a comparator circuit, a memory bit for storing the comparison results and in some embodiments the cell also comprises a range circuit. The memory may be operated in a read and write mode or it may be operated in a novel, fast search mode.
