Before entering fully into the meaning of the term flash memory, we are going to proceed to know the etymological origin of the two words that give it shape:
-Memory, in the first place, derives from Latin. Specifically, it comes from “memory”, which is the result of the sum of two lexical components: the adjective “memor”, which means “the one who remembers”, and the suffix “-ia”.
-Flash, secondly, emanates from English and it must be said that it turns out to be an onotomatopoeic voice, since it refers to the flash of light that a camera makes when it is used to take a photograph.
The Flash memory it’s a kind of chip that is used for the data storage and transfer. This technology can be found in cards, USB devices, digital cameras, MP3 players and other technological elements.
It is an evolution of the EEPROM: Electrically Erasable Programmable Read-Only Memory, that is, a kind of memory ROM (read-only) that can be electronically programmed, reprogrammed, and erased. Flash memory is therefore electronically programmable and erasable, and can also be used as a standalone storage unit.
It can be said that flash memory is an EEPROM whose programming and erasure takes place in large blocks. It’s based on semiconductors and its reading and writing are carried out through electrical impulses.
When a flash memory device is disconnected, the information on it is not lost. That is why it is possible to transport it, carrying data from a computer (computer) to another, for example.
Containing no moving parts, these memories are easy to move and use. They also stand out for their resistance and for consuming a reduced amount of Energy.
A USB flash drive, also known as pendrive, is a very useful accessory to save and read photos, music, videos and any other type of file or document. A photographer, to cite one case, can use such a flash memory to store images and then edit or display them on any computer. A writer, meanwhile, has the possibility of resorting to this technology to make a backup copy of his texts.
In addition to all the above, do not overlook the fact that there are currently two types of flash memory:
-NAND flash memory. This has in its favor that it is faster than the NOR and has the peculiarity that it needs to proceed to require what are additional mechanisms. Two characteristics that make it the necessary option when what is intended is to replace a memory card.
-NOR flash memory. This stands out, for its part, because it is slower than the previous one, but also because it gives the possibility of carrying out the random access storage. What this means is that it uses the complete data buses and also the corresponding address. For all the above, we have to indicate that it is the best option when it comes to replacing ROM memory chips.
