If you've ever heard of Xiaomi clones, you've probably heard of clone memory, a term that's often confusing: some people think of microSD cards, some people think of smartphone memory, and some people associate it with firmware altogether. It's actually more complicated and interesting.
In this article, we will explore what Xiaomi clone memory really is, why it shouldn’t be confused with regular flash memory, what kinds exist, and how to match a component to a particular model, and focus on the incompatibility risks that can turn your gadget into a brick, and also give you a checklist for safe purchase. If you’re planning a repair, upgrade, or just want to figure out the topic, read on.
What is Xiaomi’s clone and why does it need its own memory?
The term “clone” in the context of Xiaomi usually refers to non-original devices that copy the design, functionality, or even firmware of the brand.
- 📱 Replicas of popular models (for example, Redmi Note 10 Pro or POCO X3), manufactured in unlicensed factories.
- 🔧 Devices with gray components, where part of the parts (including memory) do not meet the original specifications.
- 🛠️ Homemade assemblies, where the body and motherboard from Xiaomi, and the rest of the components – from third-party manufacturers.
The main problem with these devices is hardware incompatibility. The original Xiaomi smartphones use eMMC memory or UFS Clones are often equipped with cheap analogues that are highly specific to the controllers and protocols that communicate:
- 🐢 Slower (e.g. eMMC 4.5 instead of eMMC 5.1).
- 🔥 Overheating under load.
- 🚫 Do not support original firmware functions (e.g. Dynamic) RAM Expansion in MIUI 13).
That is why repairing or upgrading clones requires a special memory that:
- It has a compatible controller (e.g. Samsung) KLMBG4WEBD hynix H9HKNNNCPMMU).
- Supports the data exchange protocol used in a particular clone model.
- It has the correct wiring of contacts on the board (even if the chip is physically fit, it may not be soldered).
⚠️ Note: If you try to install memory from the original device (or vice versa) in a Xiaomi clone, the smartphone may not turn on or malfunction. 9A It uses the Samsung 5.1 eMMC, and its clone is Micron’s cheap 4.5 eMMC with a different interface.
Memory Types for Xiaomi Clones: eMMC vs UFS vs. “hybrids»
Xiaomi clones have three main types of memory, and let's look at their differences:
| Type of memory | Speed (read/write) | Compatibility with clones | Typical problems |
|---|---|---|---|
| eMMC 4.5/5.0/5.1 | 100–250 MB/s | Most often in budget clones (Redmi). 8A, POCO C3) | Slow work, lags when multitasking |
| UFS 2.0/2.1 | 300-800 MB/s | In the clones of flagships (Mi 10, Black Shark 3) | Overheating, unstable work with custom firmware |
| "Hybrid" memory | 50–150 MB/s | In the cheapest replicas (for example, Xiaomi Note 12 Pro for 5000) ₽) | Frequent reading errors, rapid wear and tear |
eMMC is the most common variant in clones. It's cheaper. UFS, But much slower. For example, the eMMC 5.1 in the original Redmi. 9C shows the speed of reading ~200MB/s, and in the clone, it barely reaches 100MB/s because of the simplified controller. 80 percent of the lags and hangings in clones are due to poor-quality eMMC memory.
UFS It's less common, usually in flagship clones, and the main problem here is firmware incompatibility. For example, the Xiaomi Mi 11 clone can use the same name. UFS 2.1 from Kingston, but original firmware MIUI optimized UFS Samsung 3.0, and the result is the brakes on video recording. 4K or launching heavy games.
Hybrid memory is the most dangerous option, and sellers often hide it as a term:
- 🔄 Relabeled chips (e.g., eMMC 4.5, issued as 5.1).
- 🧩 Builds from a few cheap chips soldered together.
- 🗑️ B/U memory from other devices (for example, tablets).
How to Check What Memory Is In Your Xiaomi Clone
Before you buy a new memory, you need to know exactly what is installed in the device. Here are 3 reliable ways to verify:
1. through the engineering menu (for advanced users)
Open the dialing app and enter the code:
##4636##Go to the Hardware info section → Storage. Here you will see a type of memory (e.g., eMMC or eMMC). UFS) And the important thing is that in clones, this information can be forged, for example, instead of a real eMMC 4.5, it will be displayed. UFS 2.1.
2. With the help of applications
Install one of these apps from Google Play:
- 📊 AIDA64 (storage → Type of storage).
- 🔍 DevCheck (Hardware tab) → Storage).
- 🛠️ CPU-Z (section).
Look at the Manufacturer and Model fields, for example, if you see Micron. MTFC4G, This is the eMMC 4.5 and Samsung. KLUDG4U1EA — UFS 2.1.
Physical examination (for repairmen)
If you're disassembling a device, look for a marking on a memory chip, which is usually next to the processor, and it looks like a little black rectangle with a label like,
- Hynix H26M64003EMR → eMMC 5.0.
- Samsung KLM8G1WEPD → eMMC 5.1.
- Kingston FB161P32M1G → UFS 2.1.
⚠️ Note: In some clones, memory may be flooded with a compound (protective coating), and the marking will not be read without special equipment, in which case only testing or contacting the seller for specifications will help.

Where to buy memory for a clone of Xiaomi: proven sources and risks
You can buy memory for a Xiaomi clone in several places, but the risk of running into a fake or incompatible chip is very high.
1. AliExpress and other Chinese sites

How to replace memory in the clone Xiaomi: step-by-step instructions
If you decide to replace your memory yourself, follow this instruction. An error at any stage can cause the device to fail!
Preparation of tools
You'll need:
- 🔧 Screwdriver Set (Phillips #00, T3, T4).
- 🔥 Dryer or infrared soldering station (for chip unploughing).
- 🧲 Sleeve, flux, soldering iron with a thin sting.
- 🔍 Loupa or microscope (for precise soldering).
- 📱 Programmer (e.g. programmer, RT809H or CH341A) memory-stamp.
2. Dismantling the old chip
Follow the following steps carefully:
- Turn off the battery (it is better to unsold the contacts).
- Cover the board with heat resistant tape, leaving only the memory chip open.
- Heat the chip with a hairdryer to 300-350°C, until the solder melts.
- Carefully tuck the chip with tweezers and remove it.
Important: Don't overheat the board! You can't heat one section for more than 20 seconds, you can damage the tracks.
3. Installation of a new chip
Before rations:
- Clear the contacts on the board from the old solder (use the swab and flux).
- Apply a new solder to the contacts (it is better to use lead-free).
- Install the chip in place by combining contacts.
- Heat the dryer until solder melt (don't blow directly onto the chip - heat the board around!).
4. Memory firmware
After rationing:
- Connect the programmer to the memory contacts (usually CLK, CMD, DAT0, VCC, GND).
- Count the old memory dump (if possible) or download the firmware for your clone model.
- Write the firmware to new memory using a program (for example, Flash Tool for eMMC or UFS Tool for UFS).
⚠️ Note: If you use firmware from the original Xiaomi, the clone may not boot! You need modified firmware for your clone model, 4PDA) or.

Top.-5 Mistakes in the selection and replacement of memory in Xiaomi clones
Even experienced users make mistakes that lead to data loss or device failure, and these are the most common:
- Purchase memory by appearance, such as eMMC 5.1 chips and UFS 2.1 may look the same but are not interchangeable.
- Ignoring the controller, even if the memory model matches (e.g. Samsung) KLMBG4WEBD), The controller may have a different version.
- Saving on tools: soldering with a conventional soldering iron without a hair dryer often leads to detachment of contacts.
- Clones often require custom firmware with patches for non-original memory.
- Neglecting backups. If you don't backup your data before you replace it, you can't recover it!
How do you avoid mistakes?
- 🔍 Always check the chip markings against the database (for example, on the FlashIC website).
- 🛠️ Use a high-quality flux (e.g. Amtech) NC-559) solder (Sn63Pb37).
- 📥 Download firmware only from trusted sources (for example, Xiaomi.eu or thematic groups in Telegram).
💡
The most common mistake is to buy memory from AliExpress without checking compatibility. Even if the seller claims that the chip is suitable for your model, demand proof (photos of the real chip, screenshots of the tests).
