Memory module SPD comparison and programming scheme

Utilizing the WizProDDRX series programmer, perform the following operations on EEPROM/SPD chips related to DDR3/DDR4/DDR5 memory:

· SPD / Data file loading and buffer editing

Download data to the programmer for offline programming

· Chip programming, verification, and readback

· Automatic scanning and programming (barcode write buffering, error prevention, order range verification)

· Online SN increment and comparison masking

· Production information (work order, material, checker) and result log

· MES transit and result feedback (this function is non-standard and requires custom software development based on user requirements)

Standard Operating Procedure

Applicable to: scanning and programming SN and other data of chips.

1. Connect devices

Power on the programmer, fixture, and scanner; start the software (if login is required, log in first).

2. Connection port

"Search for programming device" → select scan COM → "Open scanning port".

3. Select the chip and load the data

Select the correct chip model from the dropdown list → "Load SPD Data" (or rely on automatic loading of .bin).

4. Configure basic parameters

VOUT / VPP, automatic detection of stabilization time, whether to fill in date and offset.

5. Configure SN / Masking

Set up according to engineering specifications; add comparison and shielding in the dynamic area.

6. Fill in other information

Work order, material, checker, lot, etc.

7. Configure scanning rules

Fixed code, length, write offset, fool-proof start and end codes; confirm whether to "not burn the barcode".

8. Configure MES (if available)

Load and enable MES, then save.

9. Enter mass production

Check "Enable automatic scanning and programming" → Click "Start scanning and programming function" → A programming/scanning dialog box pops up.

10. Operation rhythm

· Insert the chip (if automatic detection is enabled, wait for it to stabilize)

· Scan barcode: scan the complete barcode

· Software verification: length/fixed code/fool-proof range → (whether it is repeated on the same day) → (MES: CheckRoute transit)

· Write to the buffer after passing and perform burn-in verification

· Success: progress is blue, OK count +1; failure: red, NG +1, handle according to prompts

· When MES is enabled: End and send back OK/NG to the next station

11. Switch to a new slide and repeat; click "Exit" at the end of the workday to automatically save DDRCfgX.INI and session logs.
