Meaning of ROM Memory

What is ROM Memory:

The ROM memory It is the storage medium for programs or data that allow the proper functioning of computers or electronic devices through the reading of information without it being able to be destroyed or reprogrammed. The meaning of rom memory it is “Read Only Memory” translated to Spanish “Memory of only reading.”

ROM memory is known as non-volatile memory since the information contained in it is not erasable by turning off the electronic device.

The ROM memory is installed on the motherboard “motherboard” where the basic information of the equipment is found, called “BIOS.”

The oldest ROM memory is the MROM stores indestructible data and to update the software or data it is necessary to replace the chip which cannot be done by anyone but by an expert or the manufacturer itself, with technological advances few programs are stored in the ROM since most of them are in the new ROMs; Erasable Programmable Read-Only Memory (EPROM) is a reprogrammable and erasable memory through strong ultraviolet rays, and Electrically Erasable Programmable Read-Only Memory (FLASH EEPROM) can be reprogrammable, erasable and allows the content to be altered through signals electrical.

Since 2007 it is very difficult to find devices with ROM memory since reprogrammable devices are more flexible and cheaper.

What is ROM used for?

ROM memory is extremely important for the proper functioning of computers and electronic devices, since when the ROM memory is turned on it allows the initial program to start, which will lead to the start of the entire system.

ROM memory is used to store firmware programs, that is, store operating system programs, language interpreters, control programs (turn on the equipment); program information tables (numeric usage tables); and other programs that do not need to be constantly modified or updated.

ROM memory and RAM memory

The information contained in ROM memory is not erasable when the computer is turned off or when the power is cut off, which is why it is called non-volatile memory, while the information contained in RAM memory or volatile memory is erasable and can be erased. be lost if the user does not save the information on the computer, for example: when we write in Word, the information must be saved.

RAM memory is faster for reading than ROM memory, which is why normally the information contained in ROM memory is transferred to RAM memory.

RAM is random access memory since the information remains recorded in the electronic device and its rapid access is possible.
