ABSTRACT:
A semiconductor integrated circuit device includes a plurality of memory macros, macro-common register block, and memory macro operation setting circuits. The macro-common register block has macro-common registers which are provided outside the plurality of memory macros and supply memory macro operation specifying signals to the plurality of memory macros. The memory macro operation setting circuits are respectively provided in the plurality of memory macros and are each configured to set an operating state of the memory macro in response to the memory macro operation specifying signal supplied from the macro-common register.
