providing a plurality of key-value pairs for said associative memory array, wherein each key-value pair comprises a particular key and a constant value associated with that particular key;

compiling said key-value pairs to form a unified regular expression, said compiling comprising:

writing said unified regular expression with each of said key-value pairs having a marker between said particular key and said value for said particular key such that, for each one of said key-value pairs, said marker and said constant value form a unique tag;

further writing said unified regular expression with an “OR” logical connective between each of said key-value pairs;

determining lengths for each said particular key; and

incorporating each said particular key into said unified regular expression based on a descending order of said lengths;

forming a single liked tag by concatenating each said unique tag from all of said key-value pairs;

receiving an input string;

transforming said input string into a transformed input string by linking said input string to said single linked tag;

evaluating said transformed input string against said unified regular expression to identify a match between a single particular key located in said unified regular expression and in said transformed input string; and

retrieving, from said associative memory array, a single constant value associated with said single particular key that is located in said unified regular expression in said transformed input string; and

after identifying said match, storing said transformed input string and said single constant value.
