ABSTRACT:
A semiconductor memory device includes a plurality of independently accessible memory cores. Each memory core includes at least one flag cell storing a flag value and a plurality of data cells storing data. An access control circuit included in the semiconductor memory device selects an access-control subject memory core from the memory cores based on the flag value of the at least one flag cell of each memory core.
