Abstract
A multiprocessor system can directly transmit storage-state information in a multilink architecture. The multiprocessor system includes a first processor; a multiport semiconductor memory device coupled to the first processor; a nonvolatile semiconductor memory device; and a second processor coupled with the multiport semiconductor memory device and the nonvolatile semiconductor memory device in a multilink architecture, storing data, having been written in a shared memory area of the multiport semiconductor memory device by the first processor, in the nonvolatile semiconductor memory device, and directly transmitting storage-state information on whether the storing of the data in the nonvolatile semiconductor memory device has been completed, in response to a request of the first processor, without passing it through the multiport semiconductor memory device. Accordingly a processor indirectly coupled to a nonvolatile memory can directly check a program completion state for write data and thus enhancing a data storage performance of the system.
