Flash memory is made up of a grid of cells, each of which contains two transistors. A very
thin layer of insulating oxide separates the transistors. One serves as a control gate. The other
is a floating gate. The insulating oxide layer traps any electrons present on the floating gate,
preserving the electronic information with no need for external power. The charge of the float-
ing gate, in turn, modifies the electric field of the control gate. The voltage of this field is then
read to determine the bit value (0 or 1) of the cell.
Solid-state memory has a number of advantages. The absence of delicate mechanical ...
