SRAM devices with reduced coupling capacitance
The current disclosure is directed to a SRAM bit cell having a reduced coupling capacitance. In a vertical direction, a wordline “WL” and a bitline “BL” of the SRAM cell are stacked further away from one another to reduce the coupling capacitance between the WL and the BL. In an embodiment, the WL is vertically spaced apart from the BL with one or more metallization level that none of the WL or the BL is formed from. Connection island structures or jumper structures are provided to connect the upper one of the WL or the BL to the transistors of the SRAM cell.
