    摘要: A semiconductor memory device for use in a multiprocessor system may be provided. A chip size may be controlled, and a design of circuit may be relatively simplified. The semiconductor memory device for use in a multiprocessor system may include at least two shared memory areas commonly accessible by processors of the multiprocessor system through different ports and assigned with a predetermined memory capacity unit to a portion of a memory cell array, a single shared register adapted outside the memory cell array, corresponding to disable areas formed within the shared memory areas, and/or a switching unit for connecting a decoder of a selected shared memory area to the shared register in response to an applied control signal, to match the shared register to the disable area of the selected shared memory area. A shared register may be commonly used in corresponding to a plurality of shared memory areas, thereby reducing or preventing a chip size increase and simplifying a design of the circuit.

    摘要: A multiprocessor system includes first and second processors and a multi-path accessible semiconductor memory device including a shared memory area and a pseudo operation execution unit. The shared memory area is accessible by the first and second processors according to a page open policy. The pseudo operation execution unit responds to a virtual active command from one of the first and second processors to close a last-opened page. The virtual active command is generated with a row address not corresponding to any row of the shared memory area. For example, bit-lines of a last accessed row are pre-charged for closing the last-opened page.

The shared memory area is accessible by the processors of the multiprocessor system through different ports, and is assigned to a portion of a memory cell array. The reset signal generator is configured to provide a reset enable signal to a processor, predetermined as a slave processor among the multiple processors, for a predetermined time after an initial booting of the multiprocessor system. The reset signal generator also provides a reset disable signal to the slave processor after the predetermined time lapses.
