    • 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。

    • The induction coil of the magnetic head of the present invention is fabricated in a patterned electrical insulation material, preferably utilizing reactive ion etch (RIE) techniques. The electrical insulation material is particularly patterned such that it is formed away from the ABS surface and in the location of the induction coil. A fill layer is deposited around the patterned electrical insulation material layer, such that the fill layer is disposed at the ABS surface. In a preferred embodiment, the patterned electrical insulation material is initially fabricated from hard baked photoresist and subsequent to the deposition of the fill layer the hard baked photoresist material is removed and replaced by SiO2. The SiO2 is thereby located away from the ABS surface and the induction coil is subsequently fabricated within the SiO2 material.
    • 本发明的磁头的感应线圈以图案化的电绝缘材料制成,优选利用反应离子蚀刻(RIE)技术。 电绝缘材料被特别图案化,使得其形成为远离ABS表面并且在感应线圈的位置。 填充层沉积在图案化的电绝缘材料层周围,使得填充层设置在ABS表面。 在优选实施例中,图案化电绝缘材料最初由硬烘焙光致抗蚀剂制造,并且在沉积填充层之后,去除硬烘烤的光致抗蚀剂材料并用SiO 2替代。 因此,SiO 2 2位于离开ABS表面的位置,随后在SiO 2材料内制造感应线圈。
