Flash memory is a type of non-volatile memory that uses a similar technology to RAM, but is able to retain the data once the power is switched off.
In fact, the name is misleading as flash memory is in fact a type of storage media.
Remember from our section on Main Memory that:
Memory = running the system
Storage = saving data & programs
The development of flash memory allowed a number of advances in mobile technology as this solid state memory removed many of the issues found with portable devices:
|Portable CD players||MP3 Players||Optical drives rely on lasers and discs that spin, so are prone to skipping if knocked or rattled|
|Camera||Digital Camera||Film needed to be developed. Images could not be deleted.|
|Phone||Smart Phone||Only used for phone calls. Emails accessed on desktops.|
|Laptop HDD||Laptop SSD||Hard Disk Drproduce more heat & need more airflow. Overheating was common, reducing lifespan of components.|
