    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 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 memory device includes a pickup area extending along a first direction. The pickup area includes at least one N-pickup structure, distributing along an N-pickup line extending at the first direction. At least one P-pickup structure distributes by alternating with the N-pickup structure at the first direction and interleaves with the N-pickup structure at a second direction. The second direction is perpendicular to the first direction. Dummy pickup structure distributes along the first direction, opposite to the P-pickup structure with respect to the N-pickup line. Further, a cell area is beside the pickup area. The SRAM cells in the cell area form cell rows extending along the second direction. Each SRAM cell covers one N-type well region along the second direction and two P-type well regions along the second direction to sandwich the N-type well region. The N-pickup/P-pickup structures respectively provide first/second substrate voltage to the N-type/P-type well regions.

    Abstract: A layout configuration for a memory cell array includes at least a comb-like doped region having a first conductivity type and a fishbone-shaped doped region having a second conductivity type. The second conductivity type and the first conductivity type are complementary. Furthermore, the comb-like doped region and the fishbone-shaped doped region are interdigitated.
