We call ROM memory a type of memory present in computers and other devices and which is characterized by the fact that it cannot be written. In fact, the ROM memory was developed only to be read, although there are variants that allow a new writing in an extraordinary way, in general the use of the ROM memory remains as the only one to be read. The reason for having a memory with these characteristics is the fact that a computer and other devices need an initial program when turned on, a “first step” for the entire system . This “starting point” or set of initial processes is found in ROM memory, where they are read to execute their instructions automatically at power-up.
ROM memory is present in a computer on the so-called motherboard . It keeps important information about the equipment inside, in addition to having the recognition instructions for the various associated peripherals. As mentioned earlier, when a computer is turned on, this information starts to be used and runs various programs hosted there. If it malfunctions for any reason, the computer is unable to function. This type of structure has several years and is still in force, a circumstance that somehow highlights its usefulness. However, there are speculations that give rise to a possible end of the use of this memory in favor of other variants.
As suggested, it is possible to delete the information contained in the ROM memory through a special procedure. In fact , it replaces the content with a new one that usually comes from the manufacturer of the device in question, that is, it basically serves to carry out updates. This type of process has made it much easier in recent years in order to avoid a tremendous failure that endangers the life of the equipment.
The use of ROM memory is over forty years old and this demonstrates its importance. Over time it has undergone changes to adapt to current needs, but its use continues to extend for longer. Like many of the characteristics of computers, it was an implementation that, due to its effectiveness, had and will have a long lifespan.
