Recently the computer's application areas are changing to new realm such as cloud computing, internet of things, in-memory computing, big data and etc. and thus the amount of memory that computer needs is increased exponentially. In addition, there is a trend that the application areas that need shared memory is expanding, for example, high-performance computing, supercomputing, and so on. Since in a conventional Central Processing Unit (CPU), due to limitations of chip area, it does not have any more space to install more memory. So it is difficult to expand the memory and distributed shared memory using the I/O as in the conventional method. And it is not appropriate in the application areas that have importance at recent complex calculation and data mobility because the delay time is too long. This paper introduces the serial memory access technique that can bring the effect of the lower delay than using I/O, not taking up too much chip area of the CPU by minimizing the number of interconnections, propose the structure of the memory controller for it, and show the result of applying it to the system using actual embedded processor system. In addition, we propose a method for configuring share memory by using the serial memory access technique presented in this paper.
