Flash memory cards consist of large numbers of individual cells, each of which contains a set of transistors. Under normal circumstances, current flows between the transistors and into a drain. When a charge is applied to one of the transistors, the current flow gets blocked. The amount of current passing through the cell effectively flips it from a one to zero, allowing for the storage of binary data.Full Answer >
