HP researchers say the company could begin commercial production of memory resistors (memristors) by mid-2013, providing an alternative to today’s DRAM and flash memory. The company built the first prototype memristor a few years ago, but scientists had predicted the possibility of memristors in the 1970s. The memristor is an electronic component that takes its place alongside resistors, capacitors, and inductors.
Now scientist from HP have published a paper exploring new research into technology.
Without delving too deeply into the science, memristors are passive circuit elements which can remember the electric charge passed through them. Here’s why memristors could be exciting:
- You can build non-volatile memory with memristors, meaning that unlike DRAM they’ll retain information even when you turn off the power.
- Memristors may run 10 times faster while using 10 times less power than flash memory.
- It’s possible that memristors could eventually store data and process data — but memristor-based processors are probably further away.
Flash memory can store data when the power is turned off, but memristor-based memory could theoretically be much faster. DRAM is pretty speedy, but it requires power to retain information. That’s why a laptop will slowly lose it battery charge if you put it to sleep. Hibernation lets you preserve battery life by writing data to your hard drive or solid state disk instead, but it takes much longer to copy that data which is why it takes faster to put a computer into hibernation mode (or wake it up). Among other things, memristors could lead to faster hibernation and higher performance memory and/or storage.

This is cool stuff, but I sure wish that we could get some developments to consumers in the way of improvements in displays and batteries, both of which are needed much more than new RAM.
