Provided is a semiconductor memory cell which requires no refreshing operation for retaining information. The semiconductor memory cell comprises a first transistor TR1 having a first conductivity type, a second transistor TR2 having a second conductivity type and a MIS type diode DT for retaining information, wherein one source/drain region of the first transistor TR1 corresponds to the channel forming region CH2 of the second transistor TR2, one source/drain region of the second transistor TR2 corresponds to the channel forming region CH1 of the first transistor TR1, one end of the MIS type diode DT is formed of an extending portion of the channel forming region CH1 of the first transistor TR1, and the other end of the MIS type diode DT is constituted of an electrode which is formed of an electrically conductive material and connected to a third line having a predetermined potential.
