Sony does appear to have stockpiled or secured a large RAM supply, but I couldn’t verify a public figure for how much RAM it is buying in bulk. Recent reporting says Sony has enough supply to handle sales through the end of the next fiscal year and has already secured enough memory to avoid near-term disruption, while also saying rising memory prices are pressuring its outlook.

What’s known

  • Sony’s CFO said the company has already secured enough supply to handle sales at the end of the next fiscal year.
  • Coverage also says Sony may have “stockpiled a load of RAM modules” for PS5, though that part is framed as rumor rather than confirmed fact.
  • Sony’s broader response is to offset memory-cost pressure by leaning more on software and network services revenue.

What isn’t public

  • There is no confirmed public number for “how much RAM” Sony bought in bulk in the sources I found.
  • Bulk memory supply deals are often private, so exact quantities are usually not disclosed.

Best read on it

The safest interpretation is that Sony has locked in enough memory supply to protect its console business in the near term, but the exact bulk-buy size is not public. If your question is about PS5 console RAM specifically, reports suggest Sony planned ahead better than some rivals, but again without an exact unit count.

TL;DR

Sony is reported to have secured enough RAM supply , but the exact bulk- buy amount is not publicly known.
