Abstract
A dual port SRAM has two data storage nodes, a true data and complementary data. A first pull down transistor has an active area that forms the drain region of the first transistor and the true data storage node that is physically isolated from all other transistor active areas of the memory cell. A second pull down transistor has an active area that forms the drain region of a second transistor that is the complementary data node that is physically isolated from all other transistor active areas of the memory cell.
