ABSTRACT:
A semiconductor device includes a memory array that has dynamic memory cells. In a self refresh test mode, a self refresh test mode controller monitors and/or controls various blocks and internal signals in the semiconductor device. The self refresh test mode controller may communicate with a remote testing device through various conductors including one or more DQ lines and/or one or more address lines.
