Memory shortage spurs smartphone makers to melt used memory off old devices, then re-solder it onto new products

The smartphone industry is expected to see a spike in reballed memory adoption. According to a report by global market intelligence and research firm TrendForce, the current penetration rate is estimated at around 3–4%, with reballed memory primarily used in entry-level and budget smartphone models. However, this figure is expected to rise to 7–9% in 2027.

Reballed memory is recycled memory salvaged from older or discarded devices. The term reball comes from the process itself, in which the solder balls on a used memory chip are first melted so the chip can be removed from the old device, then re-soldered to a new device, thus allowing the component to be reused rather than discarded. You can see the process in action in the video below.

This offers manufacturers a cheaper alternative to sourcing new memory chips, potentially helping them keep production costs under control. …
