    Abstract: A static random-access memory (SRAM) cell array forming method includes the following steps. A plurality of fin structures are formed on a substrate, wherein the fin structures include a plurality of active fins and a plurality of dummy fins, each PG (pass-gate) FinFET shares at least one of the active fins with a PD (pull-down) FinFET, and at least one dummy fin is disposed between the two active fins having two adjacent PU (pull-up) FinFETs thereover in a static random-access memory cell. At least a part of the dummy fins are removed. The present invention also provides a static random-access memory (SRAM) cell array formed by said method.

    Abstract: A control circuit for a ternary content-addressable memory includes a first logic unit and a second logic unit. The first logic unit is coupled to a first storage unit, a second storage unit, a first search line, a second search line, a reference voltage terminal, and a match line. The second logic unit is coupled to the first storage unit, the second storage unit, the first search line, the second search line, a first power supply line and a second power supply line. When voltages at the first search line and the second search line match voltages at the first storage unit and the second storage unit, the second logic unit provides a path for electrically connecting the first power supply line to the second power supply line.

    Abstract: A static random access memory (SRAM) is disclosed. The SRAM includes a plurality of SRAM cells on a substrate, in which each of the SRAM cells further includes: a gate structure on the substrate, a plurality of fin structures disposed on the substrate, where each fin structure is arranged perpendicular to the arrangement direction of the gate structure, a first interlayer dielectric (ILD) layer around the gate structure, a first contact plug in the first ILD layer, where the first contact plug is strip-shaped and contacts two different fin structures; and a second ILD layer on the first ILD layer.

    Abstract: A method for forming a photo-mask is provided. A first photo-mask pattern relating to a first line, an original second photo-mask pattern relating to a first via plug, and a third photo-mask pattern relating to a second line are provided. A first optical proximity correction (OPC) process is performed. A second OPC process is performed, comprising enlarging a width of the second photo-mask pattern along the first direction to form a revised second photo-resist pattern. A contour simulation process is performed to make sure the revised second photo-mask pattern is larger or equal to the original second-mask pattern. The first photo-mask pattern, the revised second photo-mask pattern, and the third photo-mask pattern are output. The present invention further provides an OPC method.
