write-back

基本解释

In write-back mode the unit of memory access is the cache line, 64 bytes in the Core 2.
在回写式模式下，在64位机的酷睿2处理器中，存储单元路径就是缓存路线。
Typically kernels treat all RAM memory as write-back, which yields the best performance.
在这里输入译文典型的核心将所有的随机存储看作回写式，这样抑制了存储器最好的运转。
Any memory access that falls within a single cache line is guaranteed to be atomic (assuming write-back memory).
在这里输入译文任何属于单独缓存线的内存存取肯定是回写式的。

So really, the rule of thumb if you think back to Scratch is -- that any time you write a statement -- -- something that does something in one line of code -- you generally need the semicolon there.
实际上，根据经验，你们回忆一下在Scratch中,任何时候你们写一条语句-,处理一些操作的一行代码-,你们通常需要在那里加个分号。
