What is NVRAM?
Non-Volatile Random Access Memory (NVRAM) is an electronic Memory Chip that preserves data in the computer-embedded system or electronic circuit regardless of power supply integration, referring to the statement that NVRAM can store data even if the power is switched off. At the same time, standard random-access memory and dynamic access memory are different from it. Since it is dependent on power, if there is no power, the system does not work.
Due to their small memory capacities and high power requirements, they are not always appropriate for use as main memory. Additionally, because NVRAM is battery-powered, it will eventually need to be replaced.
Package options:
This equipment is available on the market as a semiconductor package. These include SIPP (Single Inline Pin Package), DIP (dual inline package), PDIP (plastic inline package), CREDIT ( ceramic dual inline package), and many more.
What are the types of NVRAM?
- RTC/Non-Volatile Random Access Memory -Are also called complementary metal-oxide-semiconductor chips. These integrate Non-Volatile Random Access Memory with a real-time clock. This particular type of clock is available to automate the data and time, which is preserved with the help of Non-Volatile Random Access Memory. RTC/Non-Volatile Random Access Memory chips are manufactured for power consumption that utilizes a low percentage of the total available power in the meantime.
- EEPROM or an electrical memory that is a non-volatile memory that preserves data that can be erased and reused conveniently and easily.
- FRAM or ferroelectric RAM, is built similarly to DRAM, but the primary distinction is that it has a thin zirconate titanate (PZT) layer. A binary switch is created when the atoms in a PZT shift polarity under an electric field. Due to this, the FRAM can maintain its data memory even when the power is turned off. This has additional advantages, like exceptionally high endurance and extremely low power usage.
Typical applications of Non-Volatile Random Access Memory
Non-Volatile Random Access Memory (NVRAM) is embedded in any electronic device that needs settings to be configured, such as the date and time. However, computer manufacturers also make use of these devices to collect information about the position of the computer system. This technology ensures that the information is stored between switched off and switched on again a particular system; in conclusion, the boot time of the system is quite fast. Many other applications for Non-Volatile Random Access Memory incorporate:
- Digital cameras
- Computer monitors
- PCs
- Tablets
- USB drives
- Smart cards
- Smartphones
