Abstract
A semiconductor memory includes a DRAM having, as seen in planar view, a first bit line and a second bit line formed on a first active area, a first cell contact formed on the first active area, and a first capacitor contact formed on the first cell contact and which is connected to a capacitor. As seen in planar view, the first cell contact is positioned closer to the second bit line than to the first bit line, and the first capacitor contact is formed offset in a direction approaching the first bit line with respect to the first cell contact.
