Phase Change Memory As A Secure Main Memory Project Report

Introduction to phase change memory:

Phase change memory technology is used for writing of the memory systems. This appears to be good technology for the design future computer memories. It has advantages when compared to that of normal DRAMs. Today’s phase change memory technology allows the memory to be written up to 107 0r 109 times and research is going on to make it suitable for the conventional technologies. This paper discusses the design of phase change main memories and it’s working.

Brief into Design and Working of phase change main memory:

When compared to that of normal DRAMs it is advantageous in terms of static energy com consumption and integration scalability. Over exceeding the limit of writing can impair its proper functioning. In 1970s the phase change memory was designed using a 256 bit semiconductor and it a non volatile memory which allows a phase change in materials. RAMs and DRAMs are designed using NAND type ash. Whereas the phase change memory storage element consists of two metal electrodes separated by resistive heater and chalcogenide and a transistor which is used for controlling the access. By reducing the wear leveling techniques the more no writes can be achieves. By bit alterable memory we change the written information from zero to one or one to zero without the use of erase step which is used in flash memories. Like DRAMs phase change memories are non volatile memories and exhibited excellent retention results when compared to DRAM.

The bandwidth and latency which supports write speed is a not upto the speed of DRAM. Certain security measures are to be taken for secured transfer of data in phase change based memories. Invisible PA to PCMA translation so that he physical address of the memories is not visible. By employing PA to PCMA translations 4K or 16k address entries can transfer into a single entry.

Water Level Indicator Minor Project

Introduction:

Water Level Indicator Minor Project aims at designing a water level indicator. A circuit is designed in such away that it indicates the level of water in the tank and gives an alarm when it is full. A CD4066 bilateral switch is connected to led to indicate water level. Certain no of electric probes are placed in the tank at certain heights for water level indication. When the water touches the electric probe the respective probe led glows. The alarm is produced by an peizo electric buzzer , which is connected to the last electric probe.

Working circuit design:

The entire circuit is designed on a bread board for the purpose of reusability, which is not possible with an soldiered board. Certain number of probes are connected to CD4066 bilateral switch and to this led is connected, when the water touches the probe the respective probe glows and at same time alarm blows. A 6V AC current is supplied to the probes, so that when the switch touches the probe it makes the switch on/off. The power supplied to the electric probe should be monitored because excess flow of current may cause electrolysis.

Applications and Future scope:

This is an effective system for knowing the level of water in the tank. This project can also be successfully implemented in minor and major projects for knowing the level of water. Instead of employing electric probes for knowing the level of water  we can also use the signaling method. The level of water is known by the time taken by the signal to come back.

Smart Window Electronics Project Report

Introduction to Smart Window Electronics Project:

The most nagging part of a summer is of course the unbearable heat generated from the sun rays gazing through our home & office windows, on contrary during winter season we wish it would be warm inside. There was a need of a glass which behaves and adjusts its characteristics depending on external weather factors. Sunrays consist of which brings harm for the human body, it is essential to cut off them before it reaches us. Smart windows are a creative and futuristic solution to all the above problems; it can be controlled like a fan is controlled by its regulator. Composite glasses are used to adjust the heat characteristics of the sunlight and also to prevent the harmful radiations from penetrating through it. All smart windows are air, water tight and are also resistant to high speed winds.  

Advantages of Smart window Electronics Project:

  • Can control the heat in the room by changing the texture of the glass electrically
  • Harmful radiations such as UV rays, Gamma rays are blocked effectively
  • Makes place warmer during winter, cooler in summer
  • Energy conservation and no need of curtain or shade fittings
  • Huge potential business in the future

SMART WINDOW TYPES:

Electro chronic window has various levels of materials such as glass panels, conducting oxides, EC Layer, Ion conductor and storage etc.  When electricity is passed through it, ions will be transferred and as a result a layer of oxide will be the positive electrode and tungsten oxide will be the negative electrode which will eventually result in darkening of the glass. In liquid crystal windows, a layer of liquid crystal are sandwiched between two films which on power supply will make the glass clear from a glazing state? Thermo chromic windows cut off heat using gel based coating changing the window state from transparent to light opaque and reflective.  Photochromic technology changes the glass color but rarely reduces the heat. Suspended particle devices (SPD) is the latest among other technologies, it contains two panels of glass, a conductive material, millions of suspended black particles, liquid suspensions and a control device. This technology can provide far more efficient cutting of heat than other technologies and also can switch the process swiftly

Fabrication of Quantum Cascade Laser Project Report

Introduction to Fabrication of Quantum Cascade Laser Project:

Fabrication of quantum cascade laser project is for M.SC students in nanoelectronics and nano mechanics. Main aim of this project is to design a new generation semiconductor laser and fabricate quantum cascade laser and gaining knowledge on semiconductors and nano technology. 

In present electronic devices semiconductors are playing important role, in this project we explain in detail about different principles used in designing cascade laser. Basically semiconductors work on inter band transitions and cascade laser operates on intra band transition of electrons. Type material will not decide the radiation wave length but it is effected by the thickness of layer in hetero structure of material. Better performance is seen in cascade laser due to series of quantum well which is implemented in hetero structure material. This procedure gives high quality and in mid infrared layer. This cascade lasers are used in different applications like gas industries, chemical industries, telecom systems and electronic counter systems, this is possible because of intra band transition property which will provide different range of wave lengths from a same material. 

In this project we use UV photolithography for structuring cascade lasers and we also use different techniques like annealing, positive photo resist, wet etching and metal evaporation. 

While designing this project special care is taken at fabrication stage. Special skills are required for engineers to protect nano device from dust contamination. Dust contamination will reduce performance and output of the laser. 

In this project report we cover details explanation on why QCL, quantum mechanics theories behind quantum cascade laser, fabrication of quantum cascade laser in nanotechnology. 

Here we provide MSC related project reports, paper presentations, seminar topics and projects with source code for free download.
