Phone Makers Turn to Reballing as Memory Prices Bite

Roughly 3–4% of smartphones today contain reballed memory chips. By 2027, market research firm TrendForce expects that figure to reach 7–9%, as manufacturers hunt for ways to keep budget phones affordable during a prolonged memory shortage.

The mechanism is simple to describe and hard to execute. A worker melts the solder balls on a used memory chip, removes it from an old or discarded device, then re-solders the same chip onto a new board. The industry calls this reballing. It lets a component be reused instead of thrown away, and it costs less than buying new silicon.

Where does reballed memory show up today?

Mostly at the bottom of the market. Reballed 4GB LPDDR4X modules dominate supply, and they land in 4G smartphones priced below CNY 1,299 — about $200. Entry-level and budget models absorb nearly all of this recycled capacity.

Price sensitivity drives the practice. Budget-segment buyers abandon a product quickly when its retail price climbs, which leaves manufacturers little room to pass costs on. Reballing offsets rising bill of materials (BOM) costs while brands hold the sticker price steady.

What does this change for the broader market?

TrendForce expects DRAM prices to rise further in the first quarter of 2027. That forecast puts more pressure on phone makers, and the research firm predicts recycled memory and other lower-specification components will gradually expand beyond the entry-level segment into more premium devices. A stopgap for cheap phones could become a general expense-management strategy across product lines.

The trend is not confined to factory floors. PC enthusiasts and hardware hobbyists are applying the same technique to desktop memory, with striking results.

The hobbyist case: $120 laptop kit becomes $1,000 desktop RAM

One electronics hobbyist recently bought an SK hynix 2x 16GB DDR5-5600 SO-DIMM kit for $120 on Facebook Marketplace, salvaged the DRAM chips, and re-balled them onto custom desktop DIMM PCBs. The finished modules reportedly reach DDR5-7800 speeds and carry a market value of around $1,000.

That project sits at the extreme end of feasibility. Converting laptop memory into desktop DIMMs demands considerable expertise and specialized equipment, and the builder needed both in volume. Smartphone reballing poses its own obstacle: modern BGA (Ball Grid Array) packages use solder connections tiny enough to defeat casual work. Repair specialists treat it as skilled labor, not routine assembly.

Still, the two developments point in the same direction. Chipmakers, repair shops, and individual builders are all finding ways to reuse existing DRAM as prices climb and availability tightens.

For smartphone buyers, the practical consequence is quiet. A budget phone in 2027 is more likely than today's model to contain a chip that already served in an earlier device, and the difference should be invisible in use. For the industry, the consequence is structural. Memory pricing now shapes sourcing strategy from the factory down to the hobbyist workbench, and TrendForce's numbers suggest the recycling channel will keep widening as long as DRAM stays expensive.
