Improving Memory Efficiency And Performance


This is the second of two parts on CXL vs. OMI. Part one can be found here. Memory pooling and sharing are gaining traction as ways of optimizing existing resources to handle increasing data volumes. Using these approaches, memory can be accessed by a number of different machines or processing elements on an as-needed basis. Two protocols, CXL and OMI, are being leveraged to simplify thes... » read more

CXL and OMI: Competing or Complementary?


System designers are looking at any ideas they can find to increase memory bandwidth and capacity, focusing on everything from improvements in memory to new types of memory. But higher-level architectural changes can help to fulfill both needs, even as memory types are abstracted away from CPUs. Two new protocols are helping to make this possible, CXL and OMI. But there is a looming question... » read more

Will Monolithic 3D DRAM Happen?


As DRAM scaling slows, the industry will need to look for other ways to keep pushing for more and cheaper bits of memory. The most common way of escaping the limits of planar scaling is to add the third dimension to the architecture. There are two ways to accomplish that. One is in a package, which is already happening. The second is to sale the die into the Z axis, which which has been a to... » read more

Aging Analysis Common Model Interface Gains Momentum


By Greg Curtis, Ahmed Ramadan, Ninad Pimparkar, and Jung-Suk Goo In February 2019, Siemens EDA wrote an article1 entitled “The Time Is Now for a Common Model Interface”. Since that time, we have continued to see increasing demand for aging analysis, not only in the traditional automotive space, but also in other areas of technology design, such as mobile communication and IoT application... » read more

Design For Reliability


Circuit aging is emerging as a mandatory design concern across a swath of end markets, particularly in markets where advanced-node chips are expected to last for more than a few years. Some chipmakers view this as a competitive opportunity, but others are unsure we fully understand how those devices will age. Aging is the latest in a long list of issues being pushed further left in the desig... » read more

Aging Analysis Standard Solidifies Through Collaborative Effort


By Ahmed Ramadan, Greg Curtis, Harrison Lee, Jongwook Kye, and Sorin Dobre We live in a connected world and it is estimated that by 20251 the total amount of worldwide data will swell to 163 ZB, or 163 trillion gigabytes. This rapid growth in data expansion is driving an explosion in new designs and new requirements for consumer, data center, automotive, and Internet of Things (IoT) applicat... » read more

The Time Is Now For A Common Model Interface


By Ahmed Ramadan and Greg Curtis Driven by consumer demand for “cheaper, faster, and better,” the semiconductor industry is continually pushing the migration to smaller process geometries. This continued scaling of complex designs into advanced process nodes is critical for applications ranging from high-performance computing to low-power mobile devices. In the past, products like sma... » read more
