EEPROM M27C512

I have a M27C512 chip that I need to copy, however, it seems as though
there is a copy protection on the chip. Is there an IC programmer
that lets you make a 1 to 1 copy of a protect IC chip.

Every time I try to do a read from the chip, all it reads is FF FF FF.
Does anyone know how to get around this.

Thanks

FAIK the component you mentioned is an ordinary EPROM that comes in two
tastes: The OTP (one time programmable) and the UV erasable (with the
wellknown window). This type of components cannot have a copy protection as
the data must stay readable.

As the other poster said, there is no copy protection on a 27512 (any
variant) and the data being FF just means that the IC is currently
blank.
