What Is Spin Torque MRAM?


The memory market is going in several different directions at once. On one front, the traditional memory types, such as DRAM and flash, remain the workhorse technologies. Then, several vendors are readying the next-generation memory types. As part of an ongoing series, Semiconductor Engineering will explore where the new and traditional memory technologies are heading. For this segment, P... » read more

New Embedded Memories Ahead


The embedded memory market is beginning to heat up, fueled by a new wave of microcontrollers (MCUs) and related chips that will likely require new and more capable nonvolatile memory types. The industry is moving on several different fronts in the embedded memory landscape. On one front, traditional solutions are advancing. On another front, several vendors are positioning the next-generatio... » read more

Material And Process Challenges In A Changing Memory Landscape


Moore’s Law has fueled the semiconductor industry’s growth for decades. But as the complexity of scaling increases, extending the economics of Moore’s Law is becoming a challenge. One example illustrating the challenges of maintaining the economic benefits of Moore’s Law is the difficulty of IC chip patterning. Today, this requires an expensive litho scanner, a complicated spacer and... » read more

Power/Performance Bits: May 24


Reducing MRAM chip area Researchers from Tohoku University developed a technology to stack magnetic tunnel junctions (MTJ) directly on the via without causing deterioration to its electric/magnetic characteristics. The team focused on reducing the memory cell area of spin-transfer torque magnetic random access memory (STT-MRAM) in order to lower manufacturing costs, making them more compe... » read more

What’s Next For DRAM?


The DRAM business has always been challenging. Over the years, DRAM suppliers have experienced a number of boom and bust cycles in a competitive landscape. But now, the industry faces a cloudy, if not an uncertain, future. On one front, for example, [getkc id="93" kc_name="DRAM"] vendors face a downturn amid a capacity glut and falling product prices in 2016. But despite the business chal... » read more

Inside The MRAM


Today, the industry is shipping various next-generation nonvolatile memory types, such as 3D NAND, MRAM and ReRAM. In fact, MRAM has been shipping for some time. To get a handle on MRAM, Semiconductor Engineering sat down to discuss the technology with Phillip LoPresti, president and chief executive of Everspin, a supplier of MRAMs. What follows are excerpts of that conversation. SE: Where ... » read more

Memory Hierarchy Shakeup


It’s no secret that today’s memory chips and storage devices are struggling to keep up with the growing demands in data processing. To solve the problem, chipmakers have been working on several next-generation memory types. But most technologies have been delayed or fallen short of their promises. But after numerous delays, a new wave of next-generation, nonvolatile memories are finally ... » read more

MRAM Begins To Attract Attention


By Mark LaPedus In the 1980s, there were two separate innovations that changed the landscape in a pair of related fields—nonvolatile memory and storage. In one effort, Toshiba invented the flash memory, thereby leading to NAND and NOR devices. On another front, physicists discovered the giant magnetoresistance (GMR) effect, a technology that forms the basis of hard disk drives, magnetores... » read more

Mixing Custom And Standard Parts


By Ed Sperling The amount of third-party and re-used IP content in an SoC is on the rise, but once a decision to buy vs. make has been made it doesn’t always stay that way. In fact, chipmakers are swinging the pendulum back and forth across a variety of chips, building IP themselves, standardizing on another vendor’s IP, then sometimes rolling it back the other way. The reasons are usua... » read more
