    摘要： A multipath accessible semiconductor memory device having a mailbox area and a mailbox access control method thereof are provided. The semiconductor memory device includes N number of ports, at least one shared memory area allocated in a memory cell array, and N number of mailbox areas for message communication. The at least one shared memory area is operationally connected to the N number of ports, and is accessible through a plurality of data input/output lines to form a data access path between the at least one shared memory area and one port, having an access right to the at least one memory area, among the N number of ports. The N number of mailbox areas are provided in one-to-one correspondence with the N number of ports and are accessible through the plurality of data input/output lines when an address of a predetermined area of the at least one shared memory area is applied to the semiconductor memory device. An efficient layout of mailboxes and an efficient message access path can be obtained.
