Unable to verify EPC16

I have an Intel flash EPC16 device. I am able to program but it always fails to verify. I have no problem with the old EPC16 device. Does anyone seeing this problem before?

Check to make sure the Byte# pin of the EPC16 is directly connected to VCC. The Intel EPC16 requires that this pin is connecting to VCC without the pull-up.
