Abstract
A single transistor type ferroelectric memory with multiple bit operation was presented. This cell has a metal ferroelectric insulator semiconductor field effect transistor structure. Y2O3 thin film was used as a buffer insulating layer to improve the memory characteristics and SrBi2Ta2O9 was used as a ferroelectric gate material. The multi-level characteristics of four levels with one order of drain current difference were measured according to the writing voltage step of two volt. This multi-level memory cell enables to increase the density of memory in the same space and lower the cost.
