Abstract: Method and apparatus for arranging and storing, in a memory, associative key data set of associative elements and a corresponding associated data set of associated elements, where each associative element corresponds to a range of consecutive values, such that an associated element may be extracted from the memory as valid data if an associative key belongs to its associative element, the range may be represented by its lower and upper extreme values. A memory device(s) is provided for storing the associative key data set and the associated data set, that comprises a first and a second storage areas, so that to each storage location in the first storage area there is a corresponding storage location in the second storage area. The associative elements of the key association data set and their corresponding associated data set are arranged in an order determined by priority precedence, such that associative elements having higher priority are placed before associative elements having lower priority.

Abstract: The bit density of stored information in a read-only memory (ROM) can be substantially increased by increasing the number of bits which can be stored in each memory cell. This can be accomplished without increasing the size or complexity of the memory cell by having the read only memory capacity stored in each memory cell as one of a multiple number of discrete states achievable by the cell. In a semiconductor chip this can be accomplished by having the semiconductor element, such as a transistor, capable of assuming one of a multiple of parametric values or states. For example, as described herein, impedance or cell width of a semiconductor transistor can be varied to assume one of four different states. The state assigned to a selected memory cell is bracketed by the value of the outputs of a plurality of comparator circuits coupled thereto.
