Abstract
Structures and static random access memory bit cells including complementary field effect transistors and methods of forming such structures and bit cells. A first complementary field-effect transistor has a first storage nanosheet transistor, a second storage nanosheet transistor stacked over the first storage nanosheet transistor, and a first gate electrode shared by the first storage nanosheet transistor and the second storage nanosheet transistor. A second complementary field-effect transistor has a third storage nanosheet transistor, a fourth storage nanosheet transistor stacked over the third storage nanosheet transistor, and a second gate electrode shared by the third storage nanosheet transistor and the fourth storage nanosheet transistor. The first gate electrode and the second gate electrode are arranged in a spaced arrangement along a longitudinal axis. All gate electrodes of the SRAM bitcell may be arranged in a 1CPP layout.
