    • An entertainment system has a music storage system storing a plurality of music pieces, a playback system coupled with the music storage system, a navigation system providing current map information including a present location, wherein a current map has a plurality of zones each being assigned to one of a plurality of zone types, and a controller for controlling playback of selected music pieces, wherein the controller maintains a plurality of playlists, each having a plurality of music pieces and being assigned to at least one zone type. The controller receives information of a present location and a current zone type and selects an assigned playlist, wherein the navigation system further provides information about a distance and/or time to a next zone. The controller modifies the assigned playlist such that a transition to the next zone is timely synchronized with the ending of a music piece of the assigned playlist.

    • An electronic data flash card accessible by a host computer, includes a flash memory controller connected to a flash memory device, and an input-output interface circuit activated to establish a communication with the host. In an embodiment, the flash card uses a USB interface circuit for communication with the host. A flash memory controller includes an arbitrator for mapping logical addresses with physical block addresses, and for performing block management operations including: storing reassigned data to available blocks, relocating valid data in obsolete blocks to said available blocks and reassigning logical block addresses to physical block addresses of said available blocks, finding bad blocks of the flash memory device and replacing with reserve blocks, erasing obsolete blocks for recycling after relocating valid data to available blocks, and erase count wear leveling of blocks, etc. Furthermore, each flash memory device includes an internal buffer for accelerating the block management operations.
    • 由主机可访问的电子数据闪存卡包括连接到闪速存储器件的闪存控制器和被激活以建立与主机的通信的输入 - 输出接口电路。 在一个实施例中,闪存卡使用USB接口电路与主机进行通信。 闪速存储器控制器包括用于将逻辑地址与物理块地址对准的仲裁器,并且用于执行块管理操作,包括:将重新分配的数据存储到可用块,将过时块中的有效数据重定位到所述可用块并将逻辑块地址重新分配给物理块地址 的所述可用块,找到闪存设备的坏块并用备用块替换,在将有效数据重新定位到可用块之后擦除用于再循环的废弃块,以及擦除块的计数损耗均衡等。此外,每个闪存设备包括 内部缓冲区,用于加快块管理操作。
