A New Memory Contender?


Momentum is building for a new class of ferroelectric memories that could alter the next-generation memory landscape. Generally, ferroelectrics are associated with a memory type called ferroelectric RAMs (FRAMs). Rolled out by several vendors in the late 1990s, FRAMs are low-power, nonvolatile devices, but they are also limited to niche applications and unable to scale beyond 130nm. While... » read more

Designing SoC Power Networks


Designing a power network for a complex SoC is becoming critical for the success of the product, but most chips are still using old techniques that are ill-suited to the latest fabrication technologies, resulting in an expensive, overdesigned product. Not only is the power network as designed too large, but this has several knock-on effects that impact area, timing and power. In the first pa... » read more

1xnm DRAM Challenges


At a recent event, Samsung presented a paper that described how the company plans to extend today’s planar DRAMs down to 20nm and beyond. This is an amazing feat. Until very recently, most engineers believed DRAMs would stop scaling at 20nm or so. Instead, Samsung is ramping up the world’s most advanced DRAMs—a line of 20nm parts—with plans to go even further. Micron and SK Hynix soo... » read more

ALD Market Heats Up


Amid the shift to 3D NAND, finFETs and other device architectures, the atomic layer deposition (ALD) market is heating up on several fronts. Applied Materials, for example, recently moved to shakeup the landscape by rolling out a new, high-throughput ALD tool. Generally, [getkc id="250" kc_name="ALD"] is a process that deposits materials layer-by-layer at the atomic level, enabling thin and ... » read more

Big Memory Shift Ahead


System architecture has been driven by the performance of [getkc id="22" kc_name="memory"]. Processor designers would have liked all of the memory be fast [getkc id="92" kc_name="SRAM"], placed on-chip for maximum performance, but that was not an option. Memory had to be fabricated as separate chips and connected via a Printed Circuit Board (PCB). That limited the number of available I/O ports ... » read more
