Default EEPROM M27C512

wrote in message
...
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.


This is an EPROM.
You can't protect an EPROM.
It has only one function - to output the data stored within.
If you stopped in outputting the data you'd be left with a useless chip that
does exactly nothing at all.

Maybe your EPROM reader is faulty?
