This is NAND flash. You cannot connect NAND flash directly as you would for SPI flash.
If it has JTAG port and if it is MIPS then it is possible to be supported but need development work to support this device.

Hi,

I found some useful information that could lead to a proper read/write:

Direct read
http://www.uchobby.com/index.php/2007/05/05/read-embedded-flash-chips/

Desoldering
https://community.saas.hpe.com/t5/Security-Research/Reverse-Engineering-NAND-Flash-Memory-POS-device-case-study-part/ba-p/280542#.WY2i062ZPaY

Clip
http://www.360-clip.com

Also, there is a video exemplifying how to read a PS3's NAND:

It'll be nice that this last one could be supported by USBJTAG NT with the help of USBBDM. More and more Arris devices are using these type of chips these days such as the case of the DG1670.
