According to
<URL:http://www.eetasia.com/ART_8800109535_499481,499486.HTM>, the
TC51W3216XB costs $26 each. I think it's too expensive (16 MB would be
$104) and too difficult to solder. And if it cannot be used in an 8-bit
configuration, then there may be problems when you want to write just one
byte without affecting the other byte in the same word.
