Typically, nonvolatile memory devices are hard disks, but they can also be solid-state devices like secure digital (SD) cards and even magnetic tape devices (all but obsolete now).

非易失性存储设备一般为硬盘，但也可以是安全数字（SD）卡之类的固态设备，甚至可以是磁带设备（不过现在已经过时了）。

Conservative extrapolation of current technology suggests that match-book size removable hard disks (or the equivalent nonvolatile memory chips) will store about 60 megabytes each.

对当前技术的保守推断表明，每个书本大小的可移动硬盘(或者等价的非易失性内存芯片)能存储大约60兆字节。

A record store is created in platform-dependent locations, like nonvolatile device memory, which are not directly exposed to the MIDlets.

记录存储在与平台相关的位置(比如非易失性设备存储器)创建，这些位置不直接公开给MIDlet。

Engineers found it too cumbersome to build a nonvolatile memory for each bit of information.

That's apparently possible by making the entire chip nonvolatile, as opposed to many current chips that only use nonvolatile merged memory.
