PROBLEM TO BE SOLVED: To provide a semiconductor storage device which can stably operate even when centralized access to the same row address occurs. ! SOLUTION: A memory 100 includes: a memory array 150; a precharge control part 111 which controls precharge of a memory cell; a row decoder 123 which outputs row selection signals for specifying row addresses of a plurality of memory cells; an integration circuit 160 which integrates the signal levels of the row selection signals for the same row address and has integral characteristics in which the integrated value of signal levels becomes a predetermined value when the row selection signals for the same row address are consecutively outputted in the predetermined number of times; and a determination part 170 which determines whether or not the integrated value of the integration circuit is equal to or greater than the predetermined value. The precharge control part 111 turns off the precharge of the memory cell when the determination part 170 determines t |
