I do believe I have already answered this question. The answer is yes. However, you need to know about electronics, how to solder, and how to remove chips from the circuit board. This isn't an easy task and takes a lot of know-how and experience to do. You will also have to understand if the memory upgrade you are trying to do will be compatible with your board. There are easier ways to increase the memory of your Android device. You can always install an SD card on the phone which you can use with the memory on your device. You can use this for storage and to set up different apps on this card.
If you actually want to go with a memory upgrade it would probably be best to go to an electronic shop or a company that does data recovery. They have a hot air solder gun that they can use to remove the chip and not damage your circuit board. If you try this on your own you can destroy the electronics of your board and the phone will be useless to you.
