[Problem to be solved] To provide a memory having set operating functions[Solution] A memory is capable of recording information at each memory address and reading the information. The memory has an input section for inputting, from outside, a first input 221 for comparing with information recorded on each memory address, a second input 222 for a comparison between each memory address, and a third input 223 as a condition for performing a set operation, the third input being selectably specified one or a combination of two or more of set operation conditions which are (1) subset, (2) logical OR, (3) logical AND, (4) logical negation; a section 208, 209 for comparing and determining information recorded on each memory address based on the first input; a section 210, 211 for comparing and determining between information recorded on the memory based on the second input; a section 224 for performing, based on the third input, a logical set operation on results determined based on the first input and the second input; and a section 207 for outputting a result of the logical set operation.
