在电脑中,存储器的速度常用它和其它部件交换单位数据的时间来表示,常用单位有: ms(毫秒,千分之一秒),如硬盘的平均存取速度17ms、12ms等。μs(微秒,百万分之一秒),如动态存储器DRAM每隔15μs更新充电一次。 ns(纳秒,十亿分之一秒),用于描述内存的速度,是最快的存储单位。不同型号规格的内存有不同的速度,如只读存储器ROM的型号有27010-20、27010-15。动态随机存储
In the computer, memory speed is often used to exchange unit data with other components of the time to express, commonly used units are: ms (milliseconds, one thousandth of a second), such as the hard disk average access speed of 17ms, 12ms and so on. μs (microseconds, millionth of a second), such as dynamic memory DRAM every 15μs update charging time. ns, nanoseconds, nanoseconds, used to describe the speed of memory, is the fastest storage unit. Different types of memory specifications have different speeds, such as ROM ROM models 27010-20,27010-15. Dynamic random access
