Abstract
A semiconductor integrated circuit incorporating DRAM 2 and a logic circuit 3 includes a vector generating circuit 40 formed on the common substrate. Upon a burn-in process, the vector generating circuit 40 and a refresh counter and control circuit 23 are activated to generate addresses, commands and data required for activating DRAM 2. In this manner, DRAM 2 and the logic circuit 3 can be activated independently, simultaneously, and the time required for the burn-in process can be reduced.
