Locate the memory package
Find the eMMC, UFS, eMCP or uMCP chip. Clean the surface gently so the laser marking is readable.

Check a mobile IC part number
Enter at least two characters. Choose an exact result to see the chip's available specifications.
- Storage capacities from common legacy and modern chips
- eMMC, UFS, eMCP, uMCP and related memory types
- Manufacturer and RAM details where available
Tip: use the longest clear marking and include its suffix when possible.

From marking to specification
Identify board storage in three careful steps
A clean reading matters. Similar-looking part numbers can represent different capacities, packages or generations.
2
Copy the complete code
Record the main alphanumeric part number. Keep hyphens and suffixes because they may distinguish closely related variants.
3
Search, then cross-check
Review the returned maker, technology and capacity. For high-value work, confirm against the board model or datasheet.
What is a mobile memory IC code?
A memory IC code is the manufacturer part number laser-marked on a semiconductor package. On smartphone motherboards, that package may contain only flash storage or combine flash storage and RAM. The code is more useful than the phone's cosmetic model name because it identifies the physical component installed on that particular board.
Technicians use part numbers to sort dead boards, verify replacement parts, estimate storage without booting a device and avoid confusing visually similar chips. A reliable lookup connects the printed marking to a known component specification.
eMMC vs UFS: what the result means
eMMC and UFS are storage standards, not capacity labels. Either technology can appear in several capacities. UFS generally offers higher throughput and can read and write simultaneously, while eMMC uses a simpler interface found across many entry-level and older devices.
| Feature | eMMC | UFS |
|---|---|---|
| Common use | Older and budget smartphones | Newer mid-range and flagship phones |
| Communication | Half-duplex | Full-duplex |
| Typical behavior | Simple, mature and cost-effective | Faster transfers and better multitasking |
| Capacity | Must be decoded from the exact part | Must be decoded from the exact part |
Why some IC results include RAM
An eMCP combines eMMC storage and mobile DRAM in one package. A uMCP similarly combines UFS storage with DRAM. That is why one part-number result may show both a storage value and a RAM value. A storage-only eMMC or UFS chip may not include any RAM specification.
How to read a faint IC marking accurately
- Disconnect power and follow normal ESD precautions before handling the board.
- Use appropriate board-cleaning methods to remove residue without damaging the package.
- Change the microscope or work-light angle; shallow light often reveals faint laser text.
- Separate the main part number from lot, date and production codes.
- Try likely alternatives for ambiguous characters such as 0/O, 1/I and 5/S.
Common mobile memory manufacturers
Mobile IC Checker covers a growing catalogue from the makers technicians encounter most often. Availability varies by part and older or region-specific components may not yet be listed.

Where IC lookup saves technicians time
A quick part-number check is useful when a phone cannot boot, a screen is unavailable or board identity is uncertain. Repair shops can verify donor parts before rework. Scrap buyers can sort boards more consistently. Wholesale dealers can label stock with better confidence, and field technicians can use the offline Android database where connectivity is unreliable.
The result is a reference, not a substitute for electrical diagnosis. Always verify critical repairs with the correct board documentation, component datasheet and professional procedures.

Mobile IC checker FAQ
Important details about part-number matching, storage results and the offline app.
What is a mobile IC code?
It is the manufacturer part number printed on a chip. For a memory package, this code can identify the maker, technology, storage capacity and sometimes the included RAM.
Can an IC code reveal a phone's storage capacity?
Yes, when the complete code matches a known part specification. Depending on the component, the result may be 16GB, 32GB, 64GB, 128GB, 256GB or another capacity.
Why does one character change the result?
Manufacturers often use closely related codes for different densities, packages and revisions. Search the full marking and pay special attention to its final letters or numeric suffix.
Does the browser IC checker work offline?
The browser checker needs internet access because it searches the current online catalogue. The Mobile IC Checker Android app includes an offline database for workshops and field use.
Which IC brands are supported?
The catalogue includes parts from Samsung, SK hynix, Micron, Kioxia, SanDisk, Kingston, YMTC, Foresee and other manufacturers. Coverage continues to grow.
What should I do if an IC code is missing?
Check ambiguous characters, remove spaces and try the main part number without unrelated lot markings. You can also contact the Mobile IC Checker team so the part can be reviewed for a future database update.
