Method to rewrite flash memory with exclusively activated two blocks and optical transceiver implementing controller performing the same

摘要

An effective algorithm for the CPU with a flash memory is disclosed to shorten a dead time to erase the flash memory and to write new data therein. The flash memory of the invention provides front and back blocks for the user data area. When the front block is filled, the back block is erased just after the front block is fully filled in advance to receive a new data next to be written.
