    • The present invention relates to a ferroelectric memory cell array formed of a single transistor, and method of storing data using the same. The ferroelectric memory cell array includes a plurality of word lines connected to gates of the memory cells located at respective rows, a plurality of bit lines connected to drains of the memory cells located at respective columns, a common source line commonly connecting sources of the memory cells, and a plurality of well lines each connected to wells in which the memory cells are each formed, wherein a bias voltage of an unit pulse shape is applied to a gate of a selected memory cell and a bias voltage of a pulse shape is applied to a well line. Therefore, the present invention allows a random access without a disturbance since data can be written by means of the polarity characteristic of the ferroelectric.
    • 本发明涉及由单个晶体管形成的铁电存储单元阵列,以及使用该晶体管存储数据的方法。 铁电存储单元阵列包括连接到位于各行的存储单元的栅极的多条字线,连接到位于相应列的存储单元的漏极的多个位线,通常连接存储器的源极的公共源极线 单元和多个井管线,每个阱管线连接到其中形成有存储单元的阱,其中单位脉冲形状的偏置电压被施加到所选存储单元的栅极并施加脉冲形状的偏置电压 到一条井线 因此,本发明允许无障碍地随机存取,因为可以通过铁电体的极性特性写入数据。
