cmos半导体_什么是CMOS（互补金属氧化物半导体）？

cmos半导体

CMOS is a short form of the complementary metal-oxide-semiconductor which is a small amount of memory generally used in computer motherboard, mainboard in order to store BIOS settings. CMOS can also be named as Real-Time Clock(RTC), CMOS RAM, Non-Volatile RAM(NVRAM), Non-Volatile BIOS Memory, and COS-MOS.

CMOS是complementary metal-oxide-semiconductor的缩写形式，它是计算机主板，主板中常用的少量内存，用于存储BIOS设置。 CMOS也可以命名为实时时钟(RTC)，CMOS RAM，非易失性RAM(NVRAM)，非易失性BIOS内存和COS-MOS。

CMOS历史 (CMOS History)

The first CMOS chip was used in early IBM computers. This CMOS chip was two main components of RTC and CMOS RAM. This CMOS also has 64-byte memory where 14 bytes were used system clock RAM and 50 bytes of storage were used for system settings.

第一个CMOS芯片用于早期的IBM计算机中。该CMOS芯片是RTC和CMOS RAM的两个主要组件。该CMOS还具有64字节的内存，其中14字节用于系统时钟RAM，而50字节的存储用于系统设置。

使用CMOS的硬件 (Hardware Using CMOS)

There is a lot of different type of computer hardware which is using the CMOS. Here are some of them.

有很多使用CMOS的不同类型的计算机硬件。这里是其中的一些。

Digital Circuits数字电路
SRAM (Static RAM)SRAM(静态RAM)
Microprocessors微处理器
Microcontrollers微控制器

CMOS的主要功能(Main Functions of CMOS)

As stated previously CMOS is used to store BIOS and Clock/Date settings.

如前所述，CMOS用于存储BIOS和时钟/日期设置。

From the beginning of the computers, BIOS data is used to stored in CMOS where there are a lot of BIOS data like boot priority, PC configuration, virtualization and GPU settings, BIOS administrative password.从计算机开始，BIOS数据就用于存储在CMOS中，其中有很多BIOS数据，例如启动优先级，PC配置，虚拟化和GPU设置，BIOS管理密码。
The clock is another important component because even a computer is disconnected from the electricity and internet it should store and track the correct date/time configuration. CMOS is used to store this date/time configuration.时钟是另一个重要组成部分，因为即使计算机断开了电源和互联网的连接，它也应该存储并跟踪正确的日期/时间配置。 CMOS用于存储此日期/时间配置。

使用CMOS重置BIOS配置 (Reset BIOS Configuration with CMOS)

CMOS stores the BIOS and Clock information where the power source is a little CMOS battery. If we need to reset the BIOS and Clock information we can remove the battery for 3-5 minutes. This will cut the power of CMOS and data stored in the CMOS ram will be lost.

CMOS存储BIOS和时钟信息，其中电源是一块CMOS电池。如果需要重置BIOS和时钟信息，我们可以在3-5分钟内取出电池。这将切断CMOS的功率，并且存储在CMOS内存中的数据将丢失。
