What If We Had Bi-Directional RRAM?

The ideal memristor device for neuromorphic computing would have linear and symmetric resistance behavior. Resistance would both increase and decrease gradually, allowing a direct correlation between the number of programming pulses and the resistance value. Real world RRAM devices, however, generally do not have these characteristics. In filamentary RRAM devices, the RESET operation can raise ... » read more

What’s Next In Neuromorphic Computing

To integrate devices into functioning systems, it's necessary to consider what those systems are actually supposed to do. Regardless of the application, [getkc id="305" kc_name="machine learning"] tasks involve a training phase and an inference phase. In the training phase, the system is presented with a large dataset and learns how to "correctly" analyze it. In supervised learning, the data... » read more

Power/Performance Bits: July 11

3D chip integrates computing, storage Researchers at Stanford University and MIT developed a prototype 3D chip that integrates computation and data storage, based on carbon nanotubes and resistive RAM (RRAM) cells. The researchers integrated over 1 million RRAM cells and 2 million carbon nanotube FETs, making what the team says is the most complex nanoelectronic system ever made with emergi... » read more

New Memories And Architectures Ahead

Memory dominates many SoCs, and it is rare to hear that a design contains too much memory. However, memories consume a significant percentage of system power, and while this may not be a critical problem for many systems, it is a bigger issue for Internet of Things ([getkc id="76" kc_name="IoT"]) edge devices where total energy consumption is very important. Memory demands are changing in al... » read more

Tech Talk: Embedded Memories

Dave Eggleston, vice president of embedded memory at GlobalFoundries, talks about the pros and cons of new types of embedded memory, including which work best for certain applications and with various advanced packaging options. [youtube vid=7D9zoA9FFIw] » read more

May The Cheapest Memory Win

There are a number of new memory types on the horizon. So why are we still using DRAM, SRAM and hard disk drives developed decades ago? The answer is complicated. Memory, whether it’s on-chip static RAM cache or off-chip dynamic RAM—or flash storage or spinning magnetic media—is really a stack of data storage technologies that need to work seamlessly together and with other non-memory ... » read more

Many Paths To Hafnium Oxide

Equipment and materials suppliers often talk about the fragmentation of integrated circuit processing. While the number of manufacturers has gone down, the diversity of the underlying semiconductor market has increased. Low-power processors for mobile devices, non-volatile memory for solid state disks, and dedicated graphics processors all have different requirements from the traditional ind... » read more

ReRAM Gains Steam

Resistive RAM appears to be gaining traction. Once considered a universal memory candidate—a replacement for DRAM, flash and SRAM—ReRAM is carving out a niche between DRAM and storage-class memory. Now the question is how large that niche ultimately becomes and whether other competing technologies rush into that space. [getkc id="94" kc_name="ReRAM"] (known alternately as RRAM), is a typ... » read more

Power/Performance Bits: Oct. 27

Searching for energy-efficient architectures A workshop jointly funded by the Semiconductor Research Corporation (SRC) and National Science Foundation (NSF) sought out the key factors limiting progress in computing – particularly related to energy consumption – and novel research that could overcome these barriers. The report focuses on the most promising research directions in the ex... » read more

Rethinking The Cloud

Data center architectures have seen very few radical changes since the commercial introduction of the [getentity id="22306" comment="IBM"] System/360 mainframe in 1964. There have been incremental improvements in speed and throughput over the years, with a move to a client/server model in the 1990s, but from a high level this is still an environment where data is processed and stored centrally ... » read more
