Abstract

A semiconductor memory device including a plurality of memory blocks each including a first command generating circuit which generates a first command; a control circuit which controls the memory core based on the first command or based on a second command inputted via the input/output port; and an arbitration circuit which outputs a first delay signal to the control circuit of one memory block of the plurality of memory blocks, the first delay signal which delays a start of an execution of the first command, in a first case when the first command generated by the first command generating circuit of the one memory block and the second command inputted via the input/output port of another memory block of the plurality of memory blocks are overlapped.
