GR-FB block cleaning scheme in flash memory.

Flash memory is a non-volatitle memory that offers several superior advantages as a data storage device in many electronic gadgets. However its two operational characteristics, namely 1) Out-place updating and 2) Cleaning process will affect its performance as an efficient storage sub-system if not...
