Abstract :
A SPICE model that predicts the self sustained operation (SSO) used in programming of a floating body cell (FBC) is presented. This model, which is calibrated to the contributions of the MOS, BJT and impact ionization (II) currents, is demonstrated to accurately predict the static and switching characteristics of the cell. Accurate modeling of device capacitances and leakages allow for quantitative estimation of static and dynamic retention of cells in an array, greatly enhancing the ability to model floating body memories.
