Quantitative Parameters of PCM Parameter DRAM NAND Flash PCM [ Boboila
This article surveys the current state of phase-change memory (PCM) as a nonvolatile memory technology set to replace flash and DRAM in modern computerized systems. It has been researched and developed in the last decade, with researchers providing better architectural designs which address the technology’s main challenges—its limited write endurance, potential long latency, high energy writes,...
متن کاملLeast squares quantization in PCM
It has long been realized that in pulse-code modulation (PCM), with a given ensemble of signals to handle, the quantum values should be spaced more closely in the voltage regions where the signal amplitude is more likely to fall. It has been shown by Panter and Dite that, in the limit as the number of quanta becomes infinite, the asymptotic fractional density of quanta per unit voltage should v...
متن کاملThe Detection of Pcm/fm
Introduction The PCM/FM detection system is shown in Fig. 1. The PCM signal is shaped using a premodulation filter, then frequency modulated and transmitted through a channel with additive gaussian noise. The received signal and noise are shaped by a predetection filter. The PCM waveform is recovered using an FM demodulator such as the discriminator, PLL or FCF, and then passed through a PCM De...
متن کاملاصول طراحی سیستمهای PCM روی کابل زوجی
هدف از این مقاله بررسی پارامترهای موثر در طرح سیستمهای PCM روی کابل زوجی است تعداد سیستمهایی که می توانند به طور رضایت بخش روی یک کابل زوجی کار کنند به وسیله نویز همشنوائی محدود می شود لذا برای بررسی این محدودیت ابتدا همشنوایی بین دو سیستم مورد توجه قرار گرفته و سپس بر اساس توزیع افت همشنوایی در کابل نتیجه برای تداخل n سیستم تعمیم داده شده نتایج به دست آمده این امکان را به وجود می آورد که بتوان...
متن کاملDetermination of the Heat Storage Capacity of Pcm and Pcm-objects as a Function of Temperature
Phase change materials (PCM) are thermal storage materials with a high storage density for small temperature range applications. One such application is the storage of natural cold of the night to use during daytime, called “free cooling”. Very high energy efficiency can be reached as the cold has not to be generated. Those systems are especially interesting for lightweight buildings, which hea...
