A shared memory control method and a user terminal for performing shared memory operation control are provided to divide a storage area of a shared memory into plural divided areas, and to enable plural processors to access each divided area, thereby minimizing data transmission time between controllers. A memory unit(310) has more than two ports, and wherein a storage area is divided into n(natural number) divided areas. Plural processors(210,220) conduct data write or read processes by accessing random divided areas through each assigned port. More than one of the n divided areas is assigned as a common storage area where one of the plural processors(210,220) having an access right can access. The access right is transferred between the plural processors(210,220), then the one of the processors(210,220) having the access right performs a data maintenance operation recorded in the common storage area.
