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.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
