Structures for a static random access memory (SRAM) bitcell and methods for forming a SRAM bitcell. The SRAM includes a storage element with a first pull-up (PU) vertical-transport field-effect transistor (VTFET) having a first bottom source/drain region and a fin projecting from the first bottom source/drain region, and a second pull-up (PU) VTFET with a second bottom source/drain region and a fin projecting from the second bottom source/drain region. The fin of the first PU VTFET is arranged over a first active region in which the first bottom source/drain region is centrally arranged, and the fin of the second PU VTFET is arranged over a second active region in which the second bottom source/drain region is centrally arranged. The second source/drain region is aligned with the first bottom source/drain region. A read port may be connected with the storage element, and may also be formed using VTFETs.
