Abstract

A memory circuit includes a memory cell and a source line transistor. The memory cell includes a first transistor, a second transistor, a third transistor, and a fourth transistor. The second transistor and the third transistor form an inverter electrically connected to a drain of the first transistor. The inverter is configured to store two states with different applied voltages. The fourth transistor is electrically connected to a node of the inverter. The source line transistor is electrically connected to the fourth transistor.
