| Samsung plans to exit the LPDDR4 manufacturing market soon |
A decade-long era is quietly coming to an end. Samsung, the world’s largest memory chip maker, is reportedly preparing to sunset its LPDDR4 and LPDDR4X production lines later this year – a move that could send shockwaves through the lower end of the electronics market.
If you’ve bought a budget smartphone, a retro gaming handheld, or a smart home sensor in the past ten years, chances are it ran on LPDDR4 memory. That’s now changing. According to a report from South Korean tech outlet The Elec, Samsung has already begun winding down production of these aging memory modules and has stopped accepting fresh orders for both LPDDR4 and LPDDR4X variants.
The writing is on the wall: existing LPDDR4/4X production lines will likely be retooled to crank out LPDDR5 chips instead, as demand for faster, more power-efficient memory shows no signs of slowing.
Why Samsung Is Walking Away from a 10-Year-Old Standard
Let’s be honest – LPDDR4 has had an incredible run. First introduced back in 2014, the standard has powered everything from the original Samsung Galaxy S6 to countless Raspberry Pi alternatives. But technology marches on.
The JEDEC (Joint Electron Device Engineering Council) has already ratified the LPDDR6 specification, and flagship chips from Apple, Qualcomm, and MediaTek are rapidly moving to newer standards. In this landscape, LPDDR5 has become the de facto choice for mid-range and non-flagship products, leaving LPDDR4 as the budget-friendly old guard.
Samsung’s decision isn’t surprising from a business perspective. Why keep fabs running on decade-old tech when LPDDR5 and LPDDR5X command higher margins and meet the needs of tomorrow’s devices? But the move will create a significant gap in the supply chain – one that many smaller OEMs didn’t see coming.
Who Gets Hurt? A Lot More Devices Than You Think
It’s easy to assume that only ancient hardware will be affected. That’s not the case.
Lower-end smartphone SoCs from Qualcomm (like the Snapdragon 4-series and 6-series), MediaTek’s Helio and Dimensity 6000 lines, and even Samsung’s own Exynos chips still rely heavily on LPDDR4X memory. These aren’t obsolete chips – they’re powering millions of budget phones sold in emerging markets today.
Beyond phones, the list of affected products is surprisingly long:
- Single-board computers (the Raspberry Pi 5, Orange Pi, and countless clones)
- IoT devices – smart speakers, security cameras, home hubs
- Cheap handheld gaming consoles (Anbernic, Retroid, and PowKiddy devices)
- Entry-level tablets and Chromebooks
- Automotive infotainment systems in non-premium vehicles
All of these will either need to upgrade to LPDDR5 – which often requires redesigned PCBs and pricier controllers – or scramble to find alternative suppliers.
The Silver Lining: SK Hynix, Micron, and a Surprise from China
Samsung isn’t the only memory maker on the planet. Both SK Hynix and Micron continue to produce LPDDR4 and LPDDR4X, and they’ll likely pick up some of the slack. But with Samsung exiting the market, supply could tighten and prices could rise – never good news for cost-sensitive devices.
That’s where a new player enters the stage.
CXMT (ChangXin Memory Technologies), a Chinese memory manufacturer, appears ready to fill the void. Another report from ETNews reveals that CXMT has partnered with GigaDevice, a fabless semiconductor company, to continue supplying LPDDR4X, DDR4, and even – believe it or not – DDR3 memory to companies that still need legacy components.
This is a smart move for CXMT. While Samsung, Hynix, and Micron race toward cutting-edge nodes, CXMT can capture the “long tail” of demand for older memory standards. For small OEMs and hobbyist-focused companies, that partnership could be a lifeline.
DDR5’s Rocketing Demand Is Also a Factor
It’s impossible to talk about Samsung’s LPDDR4 exit without mentioning the elephant in the room: DDR5 demand is absolutely exploding.
PC builders, server farms, and AI hardware providers are gobbling up every DDR5 module they can find. That’s pushed many consumers – especially those on tight budgets – to look at last-gen DDR4 alternatives instead. AMD has famously doubled down on this trend by keeping its AM4 platform alive and well, even announcing plans to relaunch the legendary Ryzen 7 5800X3D on its tenth anniversary.
The message from the market is clear: not everyone wants or needs the latest memory standard. But Samsung, as a premium player, seems comfortable leaving that segment behind.
What Should Affected Buyers and Builders Do Now?
If you’re designing a product around LPDDR4X today, you have three options:
- Move to LPDDR5 – This is the future-proof path, but it requires engineering time and higher BOM costs.
- Switch suppliers – Qualify SK Hynix or Micron LPDDR4 parts immediately. Don’t wait until Samsung’s lines are fully cold.
- Look to Chinese alternatives – CXMT/GigaDevice could become a reliable source, especially for volume orders that don’t require cutting-edge density or speed.
For individual consumers? If you’re eyeing a cheap Android phone or a $50 gaming handheld, you might want to buy sooner rather than later. Once existing LPDDR4X inventory dries up, those devices could either disappear or get a price hike when upgraded to LPDDR5.
The Bottom Line
Samsung’s decision to end LPDDR4 production marks the beginning of the end for a memory standard that quietly powered a generation of affordable electronics. It’s a classic industry shift – the leader moves on to higher margins, leaving others to fight over the scraps.
Fortunately, between SK Hynix, Micron, and emerging Chinese players like CXMT, the market won’t be left completely empty. But expect some turbulence, some redesigns, and perhaps a few nostalgic sighs from embedded engineers who’ve been happily designing with LPDDR4 for the better part of a decade.
