Garden Shed RAM: DIY Memory Cells Built From Scratch!
22 Apr
Summary
- YouTuber builds functional RAM cells in a backyard shed.
- The process replicates modern chip fabrication techniques.
- Each RAM cell is approximately microns in size.
Necessity has spurred remarkable innovation, with one individual taking extreme measures to circumvent escalating RAM costs. A YouTuber, Dr Semiconductor, has successfully built functioning memory cells in his garden shed, a feat previously thought improbable.
This endeavor involved establishing a DIY cleanroom and meticulously replicating semiconductor fabrication steps. The process, detailed in his videos, includes oxide layer deposition, photolithography, etching, and thin-film deposition, utilizing potent chemicals like hydrofluoric acid. His work offers a rare glimpse into modern chip manufacturing.
Dr Semiconductor also clarified how RAM cells function, noting their constant need for recharging due to current drain. His custom cells require recharging every few milliseconds, comparable to commercial DRAM's 64-millisecond cycles, explaining RAM's volatile nature.
The project culminated in the creation of functional RAM cells, each measuring microns in size. While a proof of concept, Dr Semiconductor plans to connect these cells to a PC, demonstrating the potential for groundbreaking DIY technology.
