Karin Werder, director of memory development at Research in Motion, told a recent industry conference that the smartphone giant is eager to get its hands on a next-generation memory technology, and the sooner the better.
Werder said RIM is looking for a “drop-in replacement” for DRAM and flash that will do everything those devices do, but with lower power consumption and higher performance, and at lower cost.
If those are the requirements, then the quest for the next-generation memory is going to be a bit of a slog. But memory makers have little choice but to soldier on.
Find out how memory makers are faring in the drive for universal memory, and which ones are the odds-on favorites to succeed, in the November edition of EE Times Confidential.
Conceptually, it's a great idea but remember: there ain't no such thing as a free lunch. There must be a strong economic argument for universal memories which are essentially a tradeoff as resistion said.
"Universal" is a distracting buzzword. "Tradeoff" is more appropriate. Eventually interconnect density vs. speed vs. power tradeoff dominates the memory performance just as for logic. For nonvolatile memory, also need to consider the inherent speed-retention tradefoff.
I find it silly to refer to "one universal memory" coming down the horizon. Bubbles were cool because you could actually set up optics to watch bubbles move (perhaps a testimony to their speed?).
Anyone remember Bubble Memory? It was going to replace both DRAM and the hard disk. Then there was some talk of EEPROM doing the same.
The problem is that the primary requirements for each stand on either sides of a wide divide - cheap enough for mass storage vs. fast enough for processing. By trying to do both with one part, you end up with something that does neither well.
I suppose it's logical to assume that someday, we will have a non-volatile memory technology that is both cheap enough to store massive amounts of video and fast enough to hook to a CPU, but I'm not holding my breath.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
