OPERATION FAILED: Device programming error. Press F3.
A device programming error is reported when a repeated attempt to program a particular cell or fuse has
failed. This error may be caused by a faulty device or an improper programming algorithm. Please check
the following:
- Improper Device Selected: Make sure the device selection matches the manufacturer and part number of
your device as precisely as possible.
- Faulty Device(s): Program at least one more device labeled with the same date/lot code. If the operation
is successful, the original device is probably faulty. If other devices with the same date/lot code fail, try
to program devices labeled with different date/lot codes. If devices with different date/lot codes are
programmed successfully, the devices from the original date/lot code are probably faulty.
- Specification Change: If this error occurs only on devices with recent date/lot codes, the devices may
require a modified programming algorithm.
See page 7-44 for more information.
OPERATION FAILED: Electronic ID verify. Press F3. (Elec. ID vfy error)
When this error occurs, the electronic ID of the device is displayed. You can also determine the ID of the
part by selecting Compare Elec ID in the Device Checks window. The Compare Elec ID parameter is also
located in the Load, Program, Verify, and Programming Parameters windows. To display the full
parameter list in the Load, Program, and Verify windows, press F4. Disabling the Electronic ID check is a
viable workaround for most memory devices.
Check the following if this error occurs:
- Improper Device Selected: Make sure the device selected matches the manufacturer and part number of
your device as precisely as possible.
- Faulty Device(s): If disabling the Compare Elec ID parameter causes an operation (Load, Program,
Verify) to fail, try the operation on other devices with the same date/lot code. If the operation is
successful on these devices, the original device may be defective.
- Manufacturer Changed Electronic ID: If the device is labeled with a recent date/lot code, the
manufacturer may have placed a new electronic ID on the device. To minimize ID errors, use the latest
version of your programmer software. If you are using the current version of programmer software,
disable the Compare Elec ID parameter.
See page 7-46 for more information.
OPERATION FAILED: Illegal bit error. Press F3.
This error indicates that at least one location in the device contains data, while its corresponding location
in RAM calls for not data to be programmed into the device. Check the following:
- Windowed Device: Perform a blank check on the device. If the blank check reports “non-blank device,”
place the device under a UV lamp and allow sufficient time for it to be erased, then reprogram the
device.
- Electronically Erasable Device: Make sure that the device’s electronic erase feature is enabled.
- One Time Programmable Device: Perform a blank check on the device. If the blank check reports “non-
blank device,” your OTP device has previously been programmed and cannot be reprogrammed.
- Faulty Device: Program at least on other device with the same date/lot code. If it programs successfully,
the original device was probably faulty. If other devices with the same date/lot code fail, program
devices with a different date/lot code. If these program correctly, the devices with the original date/lot
code are probably faulty.
