  • Publication number: 20250078917
    Abstract: An SRAM cell includes a first active region, a first gate structure, a second gate structure, and a first source/drain contact region. The first gate structure is over the first active region and forms a pull-up transistor with the first active region. The second gate structure is over the first active region and forms a write-assist transistor with the first active region. The write-assist transistor and the pull-up transistor are of a same conductivity type. The first source/drain contact region is over a source/drain of the write-assist transistor and a source/drain of the pull-up transistor.
