The History And Timeline Of Flash Memory

One of the exhibits at the Flash Memory Summit we just attended was a historical timeline. We thought it was super cool, so we are going to recreate it here. The beginning is referencing more fundamental research which are just an awesome read to understand semiconductors. As it gets to more recent times, it brings up more of the business/economic changes. Some highlights are when foundational technology was created versus when it was commercialized. It’s amazing how quickly certain technologies took off after commercialization, but also how long it others took to come to market.

In the coming weeks we will have more detailed posts about developments in flash memory, China’s YMTC, CXL, UCIe, and more in the coming weeks. Those pieces will also include more investment related information as well.
