Generally, the non-volatile memories can be expensive, have got lower performance, and have a limited lifetime when compared to the volatile RAM. Though ROM is a type of non-volatile memory, it’s not appropriate for use as the primary storage because of some limitations. The widely used type of primary storage is a volatile form of RAM or random access memory that means content present in RAM can be lost if power gets turned off. As mentioned before, it is mainly used in the computer and various electronic devices, even though the power gets turned off, data won’t disappear. Its feature is that when data gets stored, it will not be changed and deleted. ROM is a solid-state memory that will read-only data stored. In this post, we will learn more about ROM and different types of ROM to check out: What is ROM The non-volatile memory of ROM stays viable even without the power supply. ROM chips generally come built-in the external unit – just like flash drives or other auxiliary devices –and are installed in the hardware of a device on the removable chip.

You must have seen ROM chips in your computers and other electronic products game consoles, VCRs, and even car radios all of them use ROM for completing their functions effectively and smoothly.

ROM is Read-Only Memory and the most important type of electronic storage, which comes in-built to the device during manufacturing.
