IPC: H01L21/8244
Filed: 1994-09-02
Abstract: PURPOSE: To attain a sufficiently high cell ratio required for reading out the data stably by varying the work function at the gate electrode of an MOS transistor thereby making the threshold voltage variable and increasing the area of transistor. CONSTITUTION: Drive transistors Q11 , Q12 have n-type gate electrodes G11 , G12 whereas transfer transistors Q15 , Q16 have P-type gate electrodes G15 , G16 . Consequently, the gate drive voltage of the drive transistor Q11 , Q12 can be set higher than that of the transfer transistor. Since-the ON resistance per unit channel width is substantially proportional inversely to the gate drive voltage, the cell ratio is doubled when the gate drive voltage of the drive transistor Q11 , Q12 is set two times as high as that of the transfer transistor Q15 , Q16 . Consequently, the cell ratio can be quadruplicated when both the channel width and the gate drive voltage are doubled.
