1. A computer-readable memory provided with an information refinement detection function capable of storing information in each memory address, comprising: (1) an input section for entering first comparison data for being compared in parallel with each data item of the information stored in the memory and second comparison data for comparing in parallel addresses in the memory, wherein the first and second comparison data are externally provided; (2) a first determining section for determining a data match/mismatch result by comparing in parallel the each data item stored in the memory with the first comparison data; (3) a second determining section for determining a memory address match/mismatch result by comparing in parallel the addresses in the memory, according to the second comparison data; and (4) a logic operation section of the match/mismatch results of the data items and the addresses for applying a logic operation for each of the addresses and in parallel to the match/mismatch results obtained from the first determining section and the second determining section, respectively.
