HP To Introduce Flash Memory Replacement In 2013

Spy Hunter writes "Memristors are the basis of a new memory technology being developed by HP and Hynix. At the International Electronics Forum, Stan Williams, senior fellow at HP Labs, said, 'We're planning to put a replacement chip on the market to go up against flash within a year and a half. We're running hundreds of wafers through the fab, and we're way ahead of where we thought we would be at this moment in time.' They're not stopping at a flash replacement either, with Williams saying, 'In 2014 possibly, or certainly by 2015, we will have a competitor for DRAM and then we'll replace SRAM.' With a non-volatile replacement for DRAM and SRAM, will we soon see the end of the reboot entirely?"

What is old is new again.

There was a project at MIT LCS/AI back in the mid-80s to explore what it would mean to have massive amounts of RAM. A machine was designed with 1 GB of main memory. By today's standards, that's pathetic, but recall that this is in the era where PCs had 640 KB, max, and 1 GB was not only larger than every hard disk (desktop ones were at 10 MB, and even the big enterprise drives were only on order of 10 times bigger), but --- and this was the really important part -- would fill out the virtual address space, so there would be no need for a VM system. Hal Abelson and Gerry Sussman were behind these big ideas (the same duo who wrote Structure and Interpretation of Computer Programs). I don't recall if the machine was actually built (maybe it was the Digital Orrery?), but I do recall one of the contrary viewpoints being that VM was considered important not just for simulating a larger memory system, but that for type-driven hardware like Lisp Machines, a huge address space was useful because the upper addressing bits could be used to encode type, even if that address space was too large to ever be populated.
