We describe a new multiport memory which is called Shared DRAM (SHDRAM) to solve bus-bottle neck problem in parallel processor system with shared memory. This SHDRAM has four ports. Therefore four processors can be directly connected to this memory without bus-bottle neck. The basic operation of SHDRAM is confirmed by computer simulation and measurement results.
