Flash memory is a type of nonvolatile 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 whether a flash-equipped device is powered on or off.
Most flash storage systems are composed of a memory chip and an access flash controller. The memory chip is used to store data; the controller manages access to the storage space on the memory unit.The flash controller is often multi-channel, working with a RAM cache that uses only 10 percent of the total drive capacity. The cache buffers the data going to and from a number of chips.he memory chip is used to store data; the controller manages access to the storage space on the memory unit.
