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

Prototype Like A Pro


FPGA-based prototyping has been a key prototyping technique for many years. The steady increase in software content and thus the need to verify and validate the SoC in context of the software has resulted in an equally steady increase in its usage. FPGA-based prototyping or physical prototyping, as it is also called, offers a great way to develop software, verify the hardware in context of that... » read more

Power/Performance Bits: March 22


Superconducting memory A group of scientists from the Moscow Institute of Physics and Technology and the Moscow State University developed a fundamentally new type of memory cell based on superconductors, which they believe will be able to work hundreds of times faster than memory devices commonly used today. The basic memory cells are based on quantum effects in "sandwiches" of supercond... » read more

Ready For Nanoimprint?


Nanoimprint has been discussed, debated, and hyped since the term was first introduced in 1996. Now, a full 20 years later, it is being taken much more seriously in light of increasing photomask costs and delays in bringing alternatives to market. Nanoimprint lithography is something like a room-temperature UV cure embossing process. The structures are patterned onto a template or mold using... » read more

3D NAND Flash Processing


Coventor’s powerful SEMulator3D semiconductor process modeling platform offers a wide range of technology development capabilities for the development of cutting edge 3D NAND Flash Technology. 3D NAND promises high memory cell density with reduced data corruption, but also brings processing challenges. The structural complexity and inherent 3D nature of devices using 3D NAND require a predict... » read more

New Memory Approaches And Issues


New memory types and approaches are being developed and tested as DRAM and Moore's Law both run out of steam, adding greatly to the confusion of what comes next and how that will affect chip designs. What fits where in the memory hierarchy is becoming less clear as the semiconductor industry grapples with these changes. New architectures, such as [getkc id="202" kc_name="fan-outs"] and [getk... » read more

How Many Cores? (Part 1)


The optimal number of processor cores in chip designs is becoming less obvious, in part due to new design and architectural options that make it harder to draw clear comparisons, and in part because just throwing more cores at a problem does not guarantee better performance. This is hardly a new problem, but it does have a sizable list of new permutations and variables—right-sized heteroge... » read more

Optimizing DDR Memory Subsystem Efficiency


The memory subsystem sits at the core of a System-on-Chip (SoC) platform and can make all the difference between a well-designed system meeting its performance requirements and a system that delivers poor performance, or even fails to operate correctly. State-of-the-art DDR memory controllers use advanced arbitration and scheduling policies to optimize DDR memory efficiency. At the same time, t... » read more

Memory Lane: Far From A Leisurely Stroll


The only semiconductor market segment that has not been taken over by the foundries and still remains dominated by IDMs is the memory sector. The memory market is the last bastion for true IDM manufacturers, who must be savvy in the changing trends in end market applications, advanced technology development, and must still determine how much and when to invest in additional capacity. With on... » read more

Heterogeneous Multi-Core Headaches


Cache coherency is becoming more pervasive—and more problematic—as the number of heterogeneous cores used in designs continues to rise. Cache coherency is an extension of caching, which has been around since the 1970s. The notion of a cache has a long history of being utilized to speed up a computer's main memory without adding expensive new components. Cache coherency's introduction coi... » read more
