Similarly, as part of acquiring the monitor when entering a synchronized block, local caches are invalidated so that subsequent reads will go directly to main memory and not the local cache.

与此类似，作为获得监视的一部分，当进入一个同步块时，本地缓存失效，使之后的读操作直接进入主内存而不是本地缓存。

Also, each Home instance is cached once found, so that subsequent lookups will obtain it from the cache, and this cache access is protected with a synchronized block.

而且，一旦找到缓存的主机实例，随后的查找都可以从缓存中获取，这种缓存访问受到同步块的保护。

youdao

When a thread exits a synchronized block as part of releasing the associated monitor, the JMM requires that the local processor cache be flushed to main memory.

当线程为释放相关监视器而退出一个同步块时，J MM要求本地处理器缓冲刷新到主存中。

Cache's building block: six transistors that together hold a single bit.
