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.
There are many memory devices built using flash memory technology. However, USB flash drives and the Solid State Drives are the devices comparable to the function of a hard drive. Both USB flash drives and SSD are developed based on the semiconductor technology. USB flash drive is basically a flash memory chip that can be connected to computer through a USB connector.
