What is flash memory-?

Answer 1

Computing memory that retains data in the absence of a power supply i.e. it is non-volatile memory. A computer chip with a read-only memory that retains its data when the power is turned off and that can be electronically erased and reprogrammed without being removed from the circuit board, often used in fax machines. Flash memory stores computer data in a solid state format (vs. magnetic). Answer: Flash memory is a form of EAPROM (Electrically Alterable Programmable Read-Only Memory).Each bit of data in a flash memory device is stored in a transistor called a floating gate. The floating gate can only be accessed though another transistor, the control gate.The process the control gate uses to access the floating gate is a field emission phenomenon known as Fowler-Nordheim tunneling. Tunneling allows voltage to flow from the control gate to the floating gate through the dielectric layer of oxide which separates them.

Answer 2

Flash memory is a type of non-volatile memory that stores data even in the absence of power.
