Abstract
A storage device includes a first semiconductor structure having a first cell area, with memory cells disposed on a first semiconductor substrate, and a first metal pad disposed above the first cell area. A second semiconductor structure has a peripheral circuit area on a second semiconductor substrate and on which peripheral circuits are disposed, a second cell area including a plurality of second memory cells, and a second metal pad bonded to the first metal pad. A third semiconductor structure includes a memory controller disposed on a third semiconductor substrate and connected to a third metal pad through a connection via penetrating through the third semiconductor substrate. A connection structure penetrates through the second semiconductor substrate and connects the memory controller to the second semiconductor structure. The memory controller controls the first and second cell areas based on a signal applied from a host through the third metal pad.
