    • A data storage device using magnetic domain wall movement and a method of operating the same are provided to move magnetic domain walls in first and second ferromagnetic layers to record data, thereby improving stability of the magnetic domain wall movement and increasing recording density. A data storage device comprises first and second ferromagnetic layers(100,200), a data recording device(300), and multiple read heads(400a~400h). The first ferromagnetic layer has two magnetic domains(D). The second ferromagnetic layer is formed at one side of the first ferromagnetic layer to store data. The data recording device is connected with the two ferromagnetic layers. The read heads are attached to the second ferromagnetic layer. The first ferromagnetic layer is formed in a line or arc shape. The second ferromagnetic layer is partly-cut or linear-shaped.

    • PURPOSE: A phase change memory device and a computing system including the same are provided to improve a program speed by programming write data in a write memory cell of a memory cell array in a write mode and outputting a write completion signal before the phase of a write memory cell is stabilized. CONSTITUTION: A memory cell array(100) includes a plurality of phase change memory cells. A register unit(200) includes a circular queue. A control unit(300) programs write data in a write memory cell corresponding to a write address by receiving the write address and the write data in a write mode, provides the write data and the write address to the register unit, and selectively outputs a write completion signal based on a logic level of a first result signal from the register unit before or after the phase of the write memory cell is stabilized.
    • 目的:提供一种相变存储器件和包括该相变存储器件的计算系统,以通过以写入模式将存储单元阵列的写入存储器单元中的写入数据进行编程来提高编程速度,并且在相位之前输出写入完成信号 写入存储单元稳定。 构成:存储单元阵列(100)包括多个相变存储单元。 寄存器单元(200)包括循环队列。 控制单元(300)通过以写入模式接收写入地址和写入数据来将与写入地址相对应的写入存储单元中的写入数据编程,将写入数据和写入地址提供给寄存器单元,并且选择性地输出 在写入存储单元的相位稳定之前或之后,基于来自寄存器单元的第一结果信号的逻辑电平的写入完成信号。
