Abstract

PURPOSE: To overcome a defect of an associative storage system which is considered to be high in cost and to be unsuitable for converting to LSI, by sufficiently utilizing a rotary memory such as a CCD, etc.
CONSTITUTION: This comparing device is provided with one main rotary memory 10 which holds (n) number of memory cells coupled like a loop, and is capable of transferring data in the memory cell to an adjacent memory cell in the constant direction, a sub-rotary memory 11 which is capable of transferring the data in the memory cell, and (e) number of relational operators 12 for executing a relational operation designated from the control part and outputting its operation result to the comparison result controlling part. Also, in both the main rotary memory 10 and the subrotary memory 11, a data output line is provided on memory cells 13, 14 which are not coupled with the relational operators 12.
