| 术语 | dynamic circuits |
| 释义 | dynamic circuits 动态电路 A circuit which uses the absence or presence of charge on a capacitor to store information, typically with three or four transistors per cell.Fewer transistors give higher packing density and lower cost. Since the capacitor that stores the charge has a leakage current, the stored information degrades slowly and, therefore, must be refreshed periodically. 一种根据电容器上有无电荷来存储信息的电路,一般一个存储单元要用三个或四个晶体 管,较少的晶体管保证了较高的封装密度和较低的成本。由于存储电荷的电容器会漏电,存 储的信息会慢慢消失,因此必须周期性地进行刷新。 |
