Flash Storage

“Flash storage” is the generic term for any type of drive, repository, or system that uses flash memory to store data. Flash storage’s memory is a form of EEPROM (Electrically-Erasable Programmable Read-Only Memory), although flash differs from conventional EEPROM in the way that it erases data. Flash erases whole blocks of data at a time, rather than on a bit-by-bit level, as conventional EEPROM does. A block stored on a flash memory chip must be erased before new data can be written to the microchip. Unlike dynamic RAM (DRAM), standard EEPROM and flash are nonvolatile memory.
