Flash Memory

What is a flash memory?

Flash memory is a type of chip used for data storage and movement. This technology can be found in cards, USB devices, digital cameras, MP3 players and other technological elements, for example use in debit and credit cards.

Flash memory can be said to be an EEPROM (Electrically Erasable Programmable Read Only Memory) whose programming and erasing is done in large blocks. It is based on semiconductors and its reading and writing are done by electrical impulses.

A USB flash memory, also known as a pen drive, is a very useful accessory for saving and reading 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, for his part, has the possibility of resorting to this technology to make a backup copy of his texts.

How many types of flash memory are there?

NAND flash memory. This has in its favor that it is faster than the NOR and has the particularity that it needs to proceed to require what are additional mechanisms. These two characteristics make it the necessary option when the intention is to replace a memory card.

NOR flash memory. This one stands out, for its part, because it is slower than the previous one, but also because it gives the possibility of carrying out 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.
