Abstract
A memory cell of a 2-port static random access memory (SRAM) includes first and second p-type transistors and first to sixth n-type transistors. Gate interconnects extend in the X direction and are arranged in three rows in the Y direction. The gate interconnects in the first row form gates of the first n-type transistor, the first p-type transistor, and the fourth n-type transistor, the gate interconnect in the second row forms gates of the fifth and sixth n-type transistors, and the gate interconnects in the third row form gates of the third n-type transistor, the second n-type transistor, and the second p-type transistor.
