Abstract:
In an aspect of the disclosed technology, a SRAM device includes a first stack of transistors and a second stack of transistors arranged on a substrate. Each of the first and second stacks includes a pull-up transistor, a pull-down transistor and a pass transistor, where each of the transistors includes a horizontally extending channel. In each of the first and second stacks, the pull-up transistor and the pull-down transistor have a common gate electrode extending vertically therebetween, and the pass transistor has a gate electrode separated from the common gate electrode. A source/drain of each of the pull-up transistor and the pull-down transistor and a source/drain of the pass transistor included in one of the first stack and the second stack are electrically interconnected with the common gate electrode of the pull-up transistor and the pull-down transistor included in the other of the first stack and the second stack.
