摘要

本文讨论了基于富锗材料Ge2Sb2Te5 (GST)的相变存储器(PCM)中SET态电阻分布色散的增加。研究了一种新的编程技术,即线性降低存储器件有源区的温度,并给出了一种能够产生所需脉冲的电路,并进行了仿真。布局后仿真证明了电路的功能及其用于基于gst替代材料的PCM单元编程的潜力。

Optimized temperature profile based pulse generator for innovative Phase Change Memory
In this paper, we discuss the increase of the SET state resistance distribution dispersion in Phase Change Memory (PCM) based on innovative materials, namely Ge-rich Ge2Sb2Te5 (GST). A new programming technique, which consists in linearly decreasing the temperature in the active region of the memory device, is studied and a circuit capable of generating the desired pulse is presented and simulated. Post-layout simulations demonstrate the functionality of the circuit and its potential to be used for the programming of PCM cells based on alternative-to-GST materials.
