Abstract
Embodiments of present invention provide a SRAM memory. The SRAM memory includes a frontside and a backside; a first pull-up (PU) transistor stacked over a first pull-down (PD) transistor; a second PU transistor stacked over a second PD transistor; a frontside cross-couple at the frontside, above the first and second PU transistors, that connects a first source/drain (S/D) region of the first PU transistor with a gate of the second PU transistor; and a backside cross-couple, at the backside underneath the first and second PD transistors, that connects a first S/D region of the second PD transistor with a gate of the first PD transistor. A method of manufacturing the SRAM memory is also provided.
