I’ve been following alternative and persistent memory technologies for 40 years. Back in the 1980s, all we had for semiconductor memory was SRAM, DRAM, EPROM, and {non-Flash) EEPROM. During the late 1980s, when I first transitioned from working as an engineer to an editor for an electronics publication, I wrote about nascent, low-capacity, persistent memories offered by two companies located in Colorado Springs: ferroelectric memory (FRAM) made by Ramtron, and SONOS Flash memory with an SRAM shadow memory array from Simtek. Ramtron’s gone, but FRAM is still kicking, and Cypress bought Simtek in 2008. (Infineon bought Cypress in 2020.)
