→Technical details: typo, a word on error correction, and other tweaks
==Technical details==
==Technical details==
Flash memory is an efficient, non-volatile type of storage which is composed of MOSFET's that have a special "floating gate", so well insulated that it can hold its charge, thereby controlling the transistor, almost indefinitely. The charge in the floating gate can be set using electrical impulses. When disconnected from power, the transistors hold their charge, so data can be stored for quite some time and/or transferred to another device.<br />

Over a period of years (and decades) flash memory tends to suffer from bit rot. While flash memory drives are versatile and fairly reliable, they can eventually lose the data which they contain. This can make then unsuitable or long-term backups and archives, but they can often be stored for more than a decade with no discernible problem. Also, rewriting the data to the drive refreshes the electrical charges, which helps ensure that the data will be available for years to come.
Over a period of years (and decades) flash memory tends to suffer from bit rot. Since flash memory dries typically do not offer error correction functionalites as hard drives do, they can eventually lose the data they contain. While flash memory drives are versatile and fairly reliable, this can make them unsuitable or long-term backups and archives. However, they can often be stored without a data refresh for more than a decade with no discernible problem. Rewriting the data to the drive refreshes the electrical charges, which helps ensure that the data will be available for years to come.
