Flash memory

Flash memory is a special type of memory. It can be written to and overwritten similar to RAM.

However, unlike RAM, it is non-volatile so flash memory retains its contents when the computer is switched off.

Flash memory, also known as flash storage, is a type of non-volatile memory that erases data in units called blocks.

 

A block stored on a flash memory chip must be erased before data can be written or programmed to the microchip. Flash memory retains data for an extended period of time, regardless of whether a flash-equipped device is powered on or off.

Flash memory is ideal for modern smartphones, tablets, etc as it has no moving parts and requires little power. Also, it is fast to write to and to access, however it is not as fast to be read from or written to as RAM is.

TIP - Flash memory can be written to and read and it is non-volatile
