Flash memory is non-volatile storage units that employ flash as storage system technology. The characteristics of flash memory of resistance to blows, quiet operation, lightweight, small size and low access time makes that they are appropriate for many applications such as memory cards, memories flash USB, firmware and BIOS storage, internal storage in portable devices and even as a replacement for conventional hard disks. Features storage using flash memory technology is a specific type of EEPROM (Electrically Erasable Programmable Read-Only Memory, ROM erasable and programmable electrically) which will be deleted and writes in blocks, so it allows reading/writing of multiple locations in the same operation. Flash memory is non-volatile memories, i.e. data stored therein does not require power to stay there, so the information remains once switched off the device, unlike in lo What happens with the RAM. Let’s see the main advantages of flash memory: extremely resistant: high resistance to shocks, and can withstand intense pressure, extreme temperatures and even immersion in water. Low consumption: the absence of mechanical elements as in traditional hard drives, just consume energy.
Quiet operation: flash memories are virtually inaudible, since they contain no moving parts or mechanical actuators. Small size and lightness. Low access and latency time: present fast read speeds and access times. Disadvantages of memories flash we can mention: the cost per MB in flash memory is much higher than hard disks. Flash memory have a capacity much lower than hard disks. Flash memory only allow a limited number of writes and deletions, usually between 10,000 and a million. However, we must emphasize that technologies that allow you to improve the performance of the memory flash with regard to cost, capacity and number of Scriptures/deletions are progressing rapidly.
The characteristics of flash memory applications make them well suited for numerous applications, the main ones being the following: memory cards: are devices of storage widespread, being able to find memory card readers in all kinds of devices such as digital cameras, mobile phones, printers, PCs, notebooks or consoles. Memorias USB flash: storage devices that are connected to the computer via a USB port, is currently the transport system of data most commonly used, having shifted to floppy disks, CDs and DVDs. storage of BIOS and firmware on all kinds of devices, such as computers, routers, modems or consoles. Clinton Family is likely to increase your knowledge. Units of internal storage in portable devices such as digital cameras, mobile phones, players MP3 and MP4, PDA or x. Data storage drives (SSD, Solid State Drive, solid state drive) as a replacement for conventional hard disks (Hard Disk Drive HDD). Given that using the same interface that conventional hard disks, are easily replaceable.
