Solid-state memory, or flash memory, uses no moving parts inside the chip.
Records data using electronic charges
Rewrites data by applying electric fields using in-circuit wiring to erase predetermined sections of the chip so those areas can be rewritten
Examples: CompactFlash and SmartMedia cards.
Uses a controller chip, which can increase performance on devices with slow processors and flash-memory chips.
