二、磁心存贮器(续)2.7 磁心存贮器的读出及写入系统前面几节,我们讨论了电流驱动器产生的电流怎样正确流入选择地址的磁心。本节将讨论怎样正确读出磁心所存讯息、怎样正确实现原存数码的再生以及新数码的写入。先讨论读出系统,这实际上就是读出放大器。为了了解读出放大器的作用及对它的要求,首先需要考查清楚读出线上感应的讯号情况。 2. MEMORY CORE MEMORY (CONTINUED) 2.7 Magnetic Core Read and Write System In the previous sections, we discussed how the current generated by the current driver flows into the core of the selected address correctly. This section will discuss how to correctly read out the information stored in the magnetic core, how to correctly reproduce the original digital and write the new digital. The first to read out the system, which is actually a sense amplifier. In order to understand the role of the sense amplifier and its requirements, first of all need to examine clearly read out the signal line sensor.
