A YouTuber known as Dr. Semiconductor has successfully built functional DRAM memory cells in a backyard cleanroom, driven by the recent surge in memory prices attributed to AI demand. The process involved designing and fabricating a small 5x4 array of capacitors and transistors on silicon, followed by etching and doping. While the DIY memory cells demonstrated basic functionality and held a charge close to theoretical expectations, they retained it for only about 4 milliseconds, significantly less than commercial DRAM.
