| There's also FRAM, which has also been around for a while? I have an MSP430 microcontroller where the primary storage is 64kB of FRAM. It's great; performs like SRAM, but is totally persistent, and doesn't wear out. The largest devices I've seen are 4Mb (512kB), which isn't a lot by PC standards, but is dead handy for embedded. browses Oho, they make one which is pin-compatible with SRAM chips! http://www.fujitsu.com/global/products/devices/semiconductor... Price looks like $15 a single part to $12 for ten. Ouch. If we assume that it's about $20 a megabyte in bulk, a gigabyte would cost about $20k. This is, price-wise, equivalent to: - RAM, in 1996 - Spinning disk, in about 1988 - Flash, in about 1998 (extrapolation, my chart doesn't have nay data before 2004).
