Good to see an assertion of NOR applications. But is the market size large enough to drive any significant usage changes?

Read, read, read... No mention of write. Has NOR write time improved or is it as bad as it always has been?

In the last comparison, 100MHz NOR bus rate (16b bus) 50MHz NAND bus rate (8b bus) Why don't use the same freq and bus width to do comparison?

NAND parts typically don't come with a 16 bit bus and their bus rate is typically slower than the NOR parts. So the comparison seems to take these differences into account.

Posted article was truncated. From the concluding sentence: "...pin count interfaces, long product life cycles and superior..."

One significant NOR usage change is the continuing proliferation of high density SPI. As a NVM product catagory, NOR revenue is more than adequate to fund next generation process development and new product catagories.

I tried to use a typical usage case scenarios. As tb1 mentions x16 NAND is getting hard to find and commands a significant price premium. Note that even if the NAND transfer time were eliminated altogether the NOR:NAND comparision would be 50:1.

We have made significant improvements in programming performance. Spansion's GL-S product family programs at 1.2MB/s compared to the previous generation GL-P programming rate of 130KB/s.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for todays commercial processor giants such as Intel, ARM and Imagination Technologies.
