yes, the annular pcm is generally too tall when fabricated as a spacer.

Hi,Ron Neale, would you please send me your paper entitled "Nonvolatile and reprogrammable, the read-mostly memory is here" to xlzhou@mail.sim.ac.cn.

Resistion: Even if you create a PCM structure where the active material is in the form of an annulus, at sub-20nm dimensions I think the device will still have to rely on thermal cross coupling within the device structure to keep the reset current density at a level that will avoid the consequences of element separation and electro-migration. This will also mean that in a close packed matrix of those devices the device- to-device separation will be approximately the same as the the thermal coupling distant and you will suffer the consequences of thermal cross talk. In one of my earlier PCM papers in EETimes I looked briefly at a structure similar to the one you are suggesting. I characterized it as a Wrap Around Link (WAL)PCM structure and attempted to relate its likely performance to that of flat link PCM structures. If I remember it was described in a Numonyx patent. I am not aware that anybody is working on constructing memory matrix using that structure. I suppose it is just possible that it could form part of the IBM-SKH program.

A problem with the heater is it is also resistive and takes up voltage. It makes more sense for the pcm to be annular than the heater.

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.
