摘要
A planar IT2C-type ferroelectric memory cell structure which has a unit cell area of 8F(2) (F : minimum feature length) has been proposed. The minimum required area of the proposed cell is half of that of the conventional structure. The basic operation of the proposed cell has been ascertained using simulation program with integrated circuit emphasis (SPICE) simulation in which the on-off ratio of the data "readout" current of about three orders of magnitude is successfully demonstrated.
