We describe a new multiport memory which is called Shared DRAM (SHDRAM) to overcome bus-bottle neck problem in parallel processor system with shared memory. The processors are directly connected to this SHDRAM without conventional common bus. The test chip with 32kbit memory cells is fabricated using a 1.5 μm CMOS technology. The basic operation is confirmed by the circuit simulation and experimental results. In addition, it is confirmed by the computer simulation that the system performance with SHDRAM is superior to that with conventional common buses.
