Abstract:
Methods and apparatuses for static memory cells. A static memory cell may include a first pass gate transistor including a first back gate node and a second pass gate transistor including a second back gate node. The static memory cell may include a first pull down transistor including a third back gate node and a second pull down transistor including a fourth back gate node. The source node of the first pull down transistor, source node of the second pull down transistor, and first, second, third, and fourth back gate nodes are electrically coupled to each other to form a common node.
