闪存mp3扩容方法（Flash memory MP3 expansion method） Editors note: is the built-in flash memory, small volume, easy to carry the most prominent feature of the MP3 player, but also brought some unfavorable factors, that is the capacity to keep up with demand, not always expansion. The capacity of the current mainstream MP3 or 1GB, the popularity of large capacity has yet to time.

But the biggest disadvantage is the small capacity of NOR. NAND (non) flash advantage is the large capacity, this chip can store more data than the or flash, and can be done in the same storage density is cheaper. How to realize the MP3 memory expansion MP3 expansion with natural be nothing difficult expansion cards, many people are the first to buy a built-in memory relatively small MP3 days after the economic prosperity, buy a card to expand capacity.
