    • A ferroelectric memory includes a base member, a first dielectric layer formed above the base member, a second dielectric layer formed above the first dielectric layer, a contact hole that penetrates the first and second dielectric layers, a plug formed in the contact hole, and a barrier layer formed above the plug, and a ferroelectric capacitor formed from a lower electrode, a ferroelectric layer and an upper electrode successively laminated in a region including above the plug. The second dielectric layer has a property that is more difficult to be polished than the plug and the first dielectric layer.
    • 铁电存储器包括基底构件,形成在基底构件上的第一电介质层,形成在第一电介质层上方的第二电介质层,穿透第一和第二电介质层的接触孔,形成在接触孔中的插塞,以及 形成在插塞上方的阻挡层,以及由下电极,强电介质层和上电极形成的强电介质电容器,其连续地层压在包括在插塞上方的区域中。 第二电介质层具有比插塞和第一电介质层更难以抛光的性质。

    • A mobile communication apparatus configured to communicate with an opposite communication device is provided. The mobile communication apparatus includes a transceiver configured to receive an incoming signal sent from the opposite communication device. The transceiver is configured to produce an interrupt signal upon receiving the incoming signal. The mobile communication apparatus includes a first memory device and a non-volatile second memory device. The mobile communication apparatus includes a controller connected to the transceiver, the first memory device and the second memory device. The controller is configured to perform garbage collection of the second memory device, to load data stored in one of the first memory device and the second memory device into another of the first memory device and the second memory device, to access the first memory device if the transceiver produces the interrupt signal.
    • 提供了一种被配置为与相对的通信设备通信的移动通信设备。 移动通信装置包括:收发器,被配置为接收从相对的通信设备发送的输入信号。 收发器被配置为在接收到输入信号时产生中断信号。 移动通信装置包括第一存储装置和非易失性第二存储装置。 移动通信设备包括连接到收发器,第一存储器设备和第二存储器设备的控制器。 控制器被配置为执行第二存储器设备的垃圾收集,将存储在第一存储器设备和第二存储器设备之一中的数据加载到第一存储器设备和第二存储器设备中的另一个中以访问第一存储器设备,如果 收发器产生中断信号。
