Abstract: The basic concept of using the square hysteresis loop of certain magnetic memory as storage devices was known from the earliest days of computer development. Magnetic hard drives were the world’s most common means of memory storage. In this mechanically based memory system, information was stored on magnetic platters and read with magnetic heads, which hover over the disks. Hard drives were very susceptible to breakage from shaking, bumps, and falls. Data access can be slow; the magnetic reader must scan the disk magnetic section by magnetic section, looking for often-dispersed data stored on the disk. Flash memory is an alternative storage source. It stores data in solid-state transistors without moving parts. This makes the memory hardy and much less in size inclined to damage than traditional forms of storage. It also uses less power and works faster than other forms of storage. When a computer utilizing Flash is turned on, all data used in the last session reappears quickly, and without danger of corruption, as it is stored to the non-volatile, incorruptible Flash RAM. This feature makes virtually instant startup time possible, which is the reason this device majorly use on future aspects. The future of Flash technology looks bright. Less than a year ago, it was impractical due to technological and economic restrictions. However, the price of Flash memory has dropped significantly and is now rather competitive with other forms of storage but the today’s price is not competitive. The purpose of this paper is to detail the current and future technology of Flash and discuss the uses, features, and flaws of the technology. The information within this paper has been culled from professional papers, magazines, and internet sources. It also contains personal knowledge of Flash technology.
