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 |

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? -- Brian Gregory. (In the UK) To email me remove the letter vee. |

Thanks No, what that means is one of two things: A, your reader is broken or B, the EPROM has already been erased, and its contents are lost to the bit bucket. It shouldn't take long to troubleshoot your reader. Sorry, Rich |
