What are the two functions of NVRAM?
NVRAM, or non-volatile random-access memory, is a type of computer memory that can retain data even when power is removed. NVRAM is used in a variety of applications, including data storage, system configuration, and boot order settings.
NVRAM typically consists of a small amount of SRAM (static RAM) with a backing store of flash memory or EEPROM (electrically erasable programmable read-only memory). The SRAM is used to store data that must be quickly accessible, while the backing store is used to hold data that can be safely stored for longer periods of time.
There are two main functions of NVRAM: data storage and system configuration.
Data Storage
NVRAM can be used to store data that needs to be retained even when power is removed. This includes data that is constantly changing, such as system logs, or data that is only needed on an occasional basis, such as backups.
System Configuration
NVRAM can also be used to store system configuration information. This includes data such as the system's boot order, which devices are enabled, and other settings. This information is typically stored in a special area of NVRAM called the CMOS (complementary metal-oxide-semiconductor) configuration memory.
How does NVRAM work?
NVRAM (non-volatile random access memory) is a type of memory that retains data even when power is removed. NVRAM is used in a variety of applications, including computer servers, mass storage devices, and embedded systems. NVRAM is a key component in many mission-critical systems where data loss cannot be tolerated.
