摘要： A multi-path accessible semiconductor memory device having a shared memory area in a DRAM memory cell array that can be randomly accessed by a plurality of processors is provided. The multi-path accessible semiconductor memory device includes at least one shared memory area allocated in a memory cell array, operably connected to ports corresponding to a plurality of processors, each port used by the corresponding processor to selective access the shared memory area. The device further comprises an occupancy state signaling unit to output port occupancy state information to the processor requesting access to the shared memory area through the port used for the access request to indicate whether access to the shared memory area is allowed.

摘要： An interconnection layout includes alternately arranged data-read lines and data-write lines. The data-write lines are maintained at a ground voltage level when the data-read lines in a transitional state, and the data-read lines are maintained at the ground voltage level when the data-write lines in a transitional state. Therefore, a coupling capacitance is not produced between adjacent data-write lines and adjacent data-read lines.
