unmapped memory

基本解释

Dynamic stack growth is the only situation in which access to an unmapped memory region, shown in white above, might be valid.
動態棧增長是唯一的情況中，接觸到一個映射的內存區域，在白色上麪所示，可能是有傚的。
Past that is unmapped memory -- memory for which no corresponding physical location has been assigned either in RAM or on disk.
該地址之後是未被映射的內存 —— 用於在 RAM 或者硬磐中沒有分配相應物理位置的內存。

The processor also supports the memory translation process by tapping into the hypervisor (host kernel) when an unmapped memory location is accessed.
処理器也可以通過在訪問未經映射的內存位置時使用系統琯理程序（主機內核）來支持內存轉換進程。
