The 0.9 V is for read operation. It still needs 3V for write. Speed is 800 ms for write (target). Code storage is low endurance but Mb density, data is higher endurance but lower density.

@Gil Russell Did I? If you mean this announcement http://www.eetimes.com/design/memory-design/4411095/Altis-upgrades-embedded-non-volatile-memory from April 2, then I did not. If you mean something else, then possibly I did.

My apologies. Sometimes your valued contributions are overlooked. Noticed in your write-up the last part that you commented on: "..,full compatibility with standard manufacturing back-end-of-line flows, including robust data retention through the solder reflow process." said Narbeh Derhacobian, CEO of Adesto, in the same statement." A broadside on Phase Change from Narbeh - the high temperature experienced during reflow will erase it...,

Good for the start, but too early for cheer. From years ago Fujitsu and TI is promoting FRAM MCU, non-volatile RAM, which reads and writes data at 1.8V with low power consumption. Actually Panasonic also has a very talented but too closed FRAM team beside ReRAM. Panasonic still needs much more time to be able to stably manufacture and be accepted by the market. You can write infinite with FRAM, But ReRAM will always have limited write cycle(100K) which is extremely unuseful for frequent logging applications. They say smart meters as target application in the video, with 100K write, forget it.

It is surprising why Panasonic wouldn't push their FRAM.

@GermanInTI Thanks for your comment on FRAM MCU (Wolverine). However, I am not sure about ReRAM ALWAYS having limited write cycling. Some of the learned papers on metal-oxide ReRAM have shown extremely high cycling endurance. Samsung and KAIST reported on a tantalum-oxide bilayer structure (same as Panasonic) with 10^12 cycles endurance. http://www.eetimes.com/electronics-news/4217799/Samsung-trillion-cycle-ReRAM

LATEST ARCHIVED BROADCAST
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.
