Uses of Flash Memory
Flash memory is usually based on a technology called Electrically Erasable Programmable Read-Only Memory (EEPROM). EEPROM can be used to create many flash memory devices:
ROM chips
- The Read-Only Memory chips on board modern Central Processing Units (CPUs) are made from EEPROM.
- This provides the software needed for the computer to start.
Solid State Drives (SSD)
- SSDs are often used in home computers because of their performance.
- SSDs are a form of re-writable flash storage.
Secure Digital (SD) cards
- SD cards are used to extend the capacity of devices such as:
- Cameras.
- Smartphones.
- Tablets.
- They provide high capacity for their physical size. This is useful in these smaller devices.
