BrandonU from uC Hobby has come up with a clever write-up on how to read a flash chip that is already in a circuit. The idea comes from the realization that Smartmedia cards are effectively flash chips and have compatible pinout with some industry standard NAND flash chips. The device must use 8-bit blocks and share an 8-bit wide I/O for both the address and data. This is by no means an end-all solution to reading flash chips, but it may come in handy. The one part of the write up that may be problematic is inadvertently powering the board by providing power to the flash chip, but that can be looked at on a case-by-case basis.
