Abstract:

A group of new non-volatile memory technologies with characteristics making them worthy of consideration for different parts of the memory hierarchy, including the main memory, are emerging. In this thesis I discuss the state of STT-RAM, ReRAM and PCM technologies which are three of the front runners in this group of new technologies. I also simulate the performance of PCM used as main memory using Intel’s binary instrumentation framework Pin and compare it to DRAM to explore three research questions. Firstly, in the case of horizontally integrated PCM and DRAM I test a data mapping policy whe

Abstract:

The main objective of this research is to provide an efficient and reliable method for using multi-level cell (MLC) phase-change memory (PCM) as a main memory. As DRAM scaling approaches the physical limit, alternative memory technologies are being explored for future computing systems. Among them, PCM is the most mature with announced commercial products for NOR flash replacement. Its fast access latency and scalability have led researchers to investigate PCM as a feasible candidate for DRAM replacement. Moreover, the multi-level potential of PCM cells can enhance the scalability by increasin

Abstract:

Phase change memories (PCMs), based on chalcogenide alloys (mainly Ge2Sb2Te5), are the most promising candidate for the realization of “Storage Class Memories”, which would fill the gap between ‘‘operation’’ and ‘‘storage’’ memories. PCMs are also one of the few currently available technologies for the implementation of nanoeletronic synapses in high density neuromorphic systems. The main improvements needed in order to exploit the full potential of PCMs in these innovative applications are the reduction of the programming currents and power consumption, and further cell downscaling.

Abstract:

The Chip Multi-Processor (CMP) paradigm has cemented itself as the archetypal philosophy of future microprocessor design. Rapidly diminishing technology feature sizes have enabled the integration of ever-increasing numbers of processing cores on a single chip die. This abundance of processing power has magnified the venerable processor-memory performance gap, which is known as the ”memory wall”. To bridge this performance gap, a high-performing memory structure is needed. An attractive solution to overcoming this processor-memory performance gap is using compression in the memory hierarchy.

There is a growing consensus, based on several converging lines of evidence, which suggests schizophrenia is the product of a developmental insult occurring in the late 2 nd or early 3 rd trimester. Additionally, it has been observed that adults who abuse the noncompetitive NMDA antagonist PCP present with symptoms that mimic schizophrenia, such as hallucinations, formal thought disorder, delusions, unstable or flattened affect, social withdrawal, and impaired cognition. Thus, several labs have attempted to use early postnatal PCP administration in rodents as a drug model of schizophrenia. The

Abstract:

However, it is a little bit of difficult that the PCM limited by endurance, high write-in power requirement and access latency want to replace Dynamic Random Access Memory (DRAM). Therefore, to obtain better performance, the development of memory device would tend to be built in the form of DRAM-PCM Hybrid Main Memory architecture. The configuration of the total device will be allocated by the f

Abstract:

Phase Change Memory (PCM) is a recently developed non-volatile memory technology that is expected to provide an attractive combination of the best features of conventional disks (persistence, capacity) and of DRAM (access speed). For instance, it is about 2 to 4 times denser than DRAM, while providing a DRAM-comparable read latency. On the other hand, it consumes much less energy than magnetic hard disks while providing substantively smaller write latency. Due to this suite of desirable features, PCM technology is expected to play a prominent role in the next generation of computing syst

Abstract:

Chalcogenide glass based Phase Change Memories (PCMs) are being considered recently as promising alternatives to conventional non-volatile Random Access Memories (NVRAMs). PCMs offer high performance & low power consumption, in addition to other advantages, such as high scalability, high endurance and compatibility with complementary metal oxide semiconductors (CMOS) technologies. Basically PCM is a resistance variable non-volatile memory in which the memory bit state is defined by the resistance of the material. In this case, the initial ‘OFF’ state (logic zero) corresponds to the high resist

Αντικείμενο της διπλωματικής εργασίας αποτελεί η μελέτη και ανάλυση των μεθόδων διόρθωσης λαθών με χρήση κώδικα BCH που μπορούν να εφαρμοστούν σε συστήματα αποθήκευσης πληροφορίας τεχνολογίας PCM (Phase-Change Memory). Η τεχνολογία PCM αποτελεί μία νέα τεχνολογία που υπόσχεται υψηλές χωρητικότητες, χαμηλή κατανάλωση ισχύος και μπορεί να εφαρμοστεί είτε σε συσκευές αποθήκευσης σταθερής κατάστασης (Solid State Drives) είτε σε μνήμες τυχαίας προσπέλασης (Random-Access Memories), παρέχοντας μία εναλλακτική πρόταση έναντι μνημών τεχνολογίας flash και DRAM.

Abstract:

Τις τελευταίες δεκαετίες, η ανάπτυξη των non-volatile μνημών (NVMs) κατέστησε ικανή την αντικατάσταση volatile μνημών, όπως των DRAMs και των μαγνητικών σκληρών δίσκων (HDDs), σε caching και storage εφαρμογές, αντίστοιχα. Οι δίσκοι στερεάς κατάστασης (SSDs) που βασίζονται σε NAND Flash μνήμες έχουν ήδη αναδειχθεί ως ένα χαμηλού κόστους, υψηλής απόδοσης και αξιόπιστο μέσο στα σύγχρονα συστήματα αποθήκευσης. Επιπλέον, οι ιδιότητες των υλικών αλλαγής φάσης και η πρόσφατη κλιμάκωση της Phase-Change μνήμης (PCM), την καθιστά ένα τέλειο υποψήφιο για την ανάπτυξη μνημών τυχαίας προσπέλασης αλλαγής φά

PCA is currently a standard multivariate statistical technique. It has been applied to a lot of monitoring problems in chemical processes. However, the PCA model cannot explain the trend relationship among the measured variables with a small or a moderate shift in one or more process variables because it is built only based on the most recent observations.

Due to the lack of good compatibility between OBC and PCL, OBC-g-GMA (Glycidyl Methacrylate, GMA) and dicumyl peroxide (DCP) were added to improve the compatibility. In addition, ZnO with different aspect ratios were added to investigate their shape memory effect. The SEM technique confirmed the improved compatibility between OBC and PCL after modification.
