The YouTuber opens his second video on the making of his sample chips with an acknowledgment that the whole experiment has been driven by RAM prices skyrocketing last year and into the beginning of 2026, leading to vendor quotes that constantly fluctuate and even delays in broadband expansions caused by a lack of…
Key facts
- Unfortunately, the capacitors in the DIY RAM cells in his test chip were only able to hold a charge for around 4 milliseconds
- far less than commercial RAM, which he noted can retain charge for more
- If you follow PC hardware prices, you’ll know AI demand has pushed memory prices higher as manufacturers prioritize memory for datacenters
- The tests showed that the DIY RAM cells all functioned as expected, though higher voltage led to punch through due to the source and drain portions of each RAM cell being a single micron apart
- As for the capacitors in the homemade chip, each was found to be able to hold 12.3 picofarads, which was right in line with what Dr
Summary
If you follow PC hardware prices, you’ll know AI demand has pushed memory prices higher as manufacturers prioritize memory for datacenters. Semiconductor is a YouTuber who joined the platform in February and has only published two videos so far. Like any good RAM manufacturing process, Dr. He then built up microscopic layers one by one without any of the industrial automation available to Samsung, SK hynix, or Micron. After making a few small sample chips, Dr.
