PCM won't be competitive unless it can go to 20 nm with NOR capability, not this LPDDR2-NVM mix.

PCM uses very high current density for write, and voltage is not low either.

As I recall there was some delay to get this out, it was announced more than a year ago.

Price same as NAND SLC Rel equal to DRAM, 10x NOR, 100x NAnd Makes a lot of sense to use this memory Only issue is the temp.. You can't take it above boiling temp. My guess - PRAM is going to hit Ssd market and CPU market earlier than mobile

It's somewhat unfortunate their operation voltage is too high.

Yes, but this is a first-release part, so they will put in the DRAM the customers demand, and the PCM they are able to actually make... logical to expect larger PCM as soon as {if?} this hits critical-mass commercially.

"without melting the material," is then followed by "gradually induce disorder in the material until it amorphizes." - That sounds very much like melting to me... so is this an exercise in semantics, or is there some yield/lifetime gain from this new form of 'melting' ?

You are misconstruing what I said about my trading. 4x minus 1x leaves 3x. I do not think EE Times will misconstrue the negative value of our two comments.

rbtbob: I will add to Mr. Neale's comment that PCM's short electrical pulses of a few hundred nanosecond duration gradually induced disorder in your net worth until it vaporized it, as shown in your bankruptcy court letter.

What are you talking about? PCM has MUCH lower standby power than a DRAM. For this type of application (phone which is typically in standby) it will save GOBS of power.

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.
