    • A nonvolatile ferroelectric memory device is provided so as to control read/write operations of a nonvolatile memory cell using a channel resistance of the memory cell which is differentiated by polarity states of a ferroelectric material. In the memory device, an insulating layer is formed on a bottom word line, and a floating channel layer comprising a N-type drain region, a P-type channel region and a N-type source region is formed on the insulating layer. Then, a ferroelectric layer is formed on the floating channel layer, and a word line is formed on the ferroelectric layer. As a result, the resistance state induced to the channel region is controlled depending on the polarity of the ferroelectric layer, thereby regulating the read/write operations of the memory cell array.
    • 提供非易失性铁电存储器件,以便使用由铁电材料的极性状态区分的存储单元的沟道电阻来控制非易失性存储单元的读/写操作。 在存储器件中,在底部字线上形成绝缘层,并且在绝缘层上形成包括N型漏极区,P型沟道区和N型源极区的浮动沟道层。 然后,在浮动沟道层上形成铁电体层,在铁电体层上形成字线。 结果,根据铁电层的极性来控制感应到沟道区的电阻状态,从而调节存储单元阵列的读/写操作。
