Register File Design at the 5nm Nodeby Tom Dillinger on 03-10-2021 at 2:00 pmCategories: Events, Foundries, TSMC
“What are the tradeoffs when designing a register file?” Engineering graduates pursuing a career in microelectronics might expect to be asked this question during a job interview. (I was.)
On the surface, one might reply, “Well, a register file is just like any other memory array – address inputs, data inputs and outputs, read/write… Read More
There are reports in the media that TSMC is now planning six Fabs in Arizona (the image above is Fab 18 in Taiwan). The original post I saw referred to a Megafab and claimed six fabs with 100,000 wafers per month of capacity (wpm) for $35 billion dollars. The report further claimed it would be larger than TSMC fabs in Taiwan.
This report… Read More
Resistive RAM (ReRAM) technology has emerged as an attractive alternative to embedded flash memory storage at advanced nodes. Indeed, multiple foundries are offering ReRAM IP arrays at 40nm nodes, and below.
ReRAM has very attractive characteristics, with one significant limitation:
- nonvolatile
- long retention time
- extremely

Now that semiconductor conferences are virtual there are better speakers since they can prerecord and we have the extra time to do a better job of coverage. Even when conferences go live again I think they will also be virtual (hybrid) so our in depth coverage will continue.
ISSCC is one of the conferences we covered live since it’s… Read More
It is quite amazing that silicon-based devices have been the foundation of our industry for over 60 years, as it was clear that the initial germanium-based devices would be difficult to integrate at a larger scale. (GaAs devices have also developed a unique microelectronics market segment.) More recently, it is also rather … Read More
The vast majority of the attention given to the introduction of each new advanced process node focuses on lithographic updates. The common metrics quoted are the transistors per mm**2 or the (high-density) SRAM bit cell area. Alternatively, detailed decomposition analysis may be applied using transmission electron microscopy… Read More
Design Considerations for 3DICsby Tom Dillinger on 12-14-2020 at 6:00 amCategories: Events, Foundries, TSMC
The introduction of heterogeneous 3DIC packaging technology offers the opportunity for significant increases in circuit density and performance, with corresponding reductions in package footprint. Yet, the implementation of a complex 3DIC product requires a considerable investment in methodology development for all… Read More
Bloomberg did an interview with my favorite semiconductor analyst Stacy Rasgon on “How the Number One U.S. Semiconductor Company Stumbled” that I found interesting. Coupled with the Q&A Bob Swan did at the Credit Suisse Annual Technology Conference I thought it would be good content for a viral blog.
Stacy Rasgon… Read More
Seeking Alpha just published an article about Intel and Samsung passing TSMC for process leadership. The Intel part seems to be a theme with them, they have talked in the past about how Intel does bigger density improvements with each generation than the foundries but forget that the foundries are doing 5 nodes in the time it takes… Read More
The semiconductor foundry business has been front page news of late and for good reason, it’s an exciting time in the semiconductor industry and the foundries are where it all begins. Unfortunately, most of the “exciting” news has been overblown but this topic is of great interest, to me at least. Having been intimately involved… Read More
