"reading sth to memory" 和 "reading sth into memory" 是什么意思

what does it mean by "reading sth to memory" and "reading sth into memory"

关于 readwrite 操作,我只知道 read 操作从某处读取数据,而 write 操作将数据存储到内存中。话虽如此,read sth from memorywrite sth to memory 是完全可以理解的,但 read sth into memory 以及 read sth to memory 对我来说毫无意义。

从CPU的角度来看,read sth into memoryread sth to memory通常意味着将数据从磁盘(或其他慢得多的设备)加载到内存。
