IBM develops 'instantaneous' memory, 100x faster than flash

  You've got to hand it to IBM's engineers. They drag themselves into work after their company's 100th birthday party, and then promptly announce yet another seismic invention. This time it's a new kind of phase change memory (PCM) that reads and writes 100 times faster than flash, stays reliable for millions of write-cycles (as opposed to just thousands with flash), and is cheap enough to be used in anything from enterprise-level servers all the way down to mobile phones. 
PCM is based on a special alloy that can be nudged into different physical states, or phases, by controlled bursts of electricity. In the past, the technology suffered from the tendency of one of the states to relax and increase its electrical resistance over time, leading to read errors. Another limitation was that each alloy cell could only store a single bit of data. But IBM employees burn through problems,  not only is their latest variant more reliable, it can also store four data bits per cell, which means we can expect a data storage "paradigm shift" within the next five years. 

As the Press Release says : 

  • Reliable multibit phase-change memory technology demonstrated
  • Scientists achieved a 100 times performance increase in write latency compared to Flash.
  • Enables a paradigm shift for enterprise IT and storage systems, including cloud computing by 2016.

ZURICH, June 30, 2011 – For the first time, scientists at IBM Research have demonstrated that a relatively new memory technology, known as phase-change memory (PCM). ( Now actually, PCM ( also known as  Chalcogenide RAM and C-RAM) is a type of non-volatile computer memory. PRAMs exploit the unique behavior of chalcogenide glass. With the application of heat produced by the passage of an electric current, this material can be "switched" between two states, crystalline and amorphous. ) 
Unlike Flash, PCM is also very durable and can endure at least 10 million write cycles, compared to current enterprise-class Flash at 30,000 cycles or consumer-class Flash at 3,000 cycles. While 3,000 cycles will out live many consumer devices, 30,000 cycles are orders of magnitude too low to be suitable for enterprise applications
Here is some of the stuff regarding the 'inside' the technology (in which all are not interested), but as i am electronic engineer , i am kinda interested in it. So read further if you really want to know about the technology. 

PCM leverages the resistance change that occurs in the material -- an alloy of various elements -- when it changes its phase from crystalline –featuring low resistance – to amorphous – featuring high resistance – to
store data bits. In a PCM cell, where a phase-change material is deposited between a top and a bottom electrode, phase change can controllably be induced by applying voltage or current pulses of different strengths. These heat up the material and when distinct temperature thresholds are reached cause the material to change from crystalline to amorphous or vice versa.

In addition, depending on the voltage, more or less material between the electrodes will undergo a phase change, which directly affects the cell's resistance. Scientists exploit that aspect to store not only one bit, but multiple bits per cell. In the present work, IBM scientists used four distinct resistance levels to store the bit combinations "00", "01" 10" and "11".

Using that technique, the IBM scientists were able to mitigate drift and demonstrate long- term retention of bits stored in a subarray of 200,000 cells of their PCM test chip, fabricated in 90-nanometer CMOS technology.

The Unseen Wonders Of World

Now, probably you may know some (or all or none) of the wonders of the world which are listed here, but i just wanted to share with you. Most of the people un-notice them. So a brief introduction to such wonders of world. Yeah, all are natural wonders, because i think in this century NATURE is going unnoticed to mankind. 

World's Top 10 and Best Natural Phenomenon -The Pictures You Don't want to miss.
Follow us on Twitter

 1. The Great Barrier Reef
It is located on the eastern coast of Australia is indeed a natural wonder created by polyp (in the picture) -an organism measuring just 8 mm. The reef is made of coral is 2030 Km long and 60 to 160 Km wide. It stretches in an area of 3,44,400 square Km. Now, the great barrier reef has a set a world record of being.......Any Guess?

The largest construction ever made by a living being. There is no construction in the world as large as this reef, which constructed  by the many generation of polyp for millions of years.The area covered by reef system is equivalent area covered by 80,00,000 Khufu pyramids of Egypt.
The Great Barrier Reef is the world's largest reef system composed of over 2,900 individual reefs and 900 islands. The Great Barrier Reef can be seen from outer space and selected as a World Heritage Site in 1981.

2. Ayers Rock 
Ayers Rock - a flat surfaced sandstone  rock , in central Australia, is 335 meters  high, 3.6 Km long and 2 Km wide This rock is considered as a natural wonder in many ways. For instance, according to Geologist minimum 2,000 meters of rock is underground ,just like an iceberg. 
The most significant is, Rock changes it colors throughout the day.Ayers Rock also know as Uluru. Average composition is 50% feldspar, 25–35% quartz and up to 25% rock fragments. During the day time, based on the angle of the sun rays, certain colors are reflected by these elements.The reflection of the color keeps on changing based on the sun-ray's angles.

3.Giant's Causeway
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption. It is located on the northeast coast of Northern Ireland. It was declared a World Heritage Site by UNESCO in 1986.The Giant's Causeway was named as the fourth greatest natural wonder in the United Kingdom.
The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven and eight sides. The tallest are about 12 metres (39 ft) high, and the solidified lava in the cliffs is 28 metres thick in places.
The Giant's Boot
Basalt columns
Some of the structures in the area, having been subject to several million years of weathering, resemble objects, such as the Organ and Giant's Boot structures. Other features include many reddish, weathered low columns known as Giants Eyes, created by the displacement of basalt boulders; the Shepherd's Steps; the Honeycomb; the Giant's Harp; the Chimney Stacks; the Giant's Gate and the Camel's Hump.

4. Iguazu Falls
Iguazu Falls are waterfalls of the Iguazu River located on the border of the Brazil and the Argentine.
Numerous islands along the 2.7-kilometre long edge divide the falls into about 275 separate waterfalls and cataracts, varying between 60 metres and 82 metres high. About half of the river's flow falls into a long and narrow chasm called the Devil's Throat.
Devil's Throat
Upon seeing Iguazu, the United States' First Lady Eleanor Roosevelt reportedly exclaimed "Poor Niagara!"
Iguazu currently has the second greatest average annual flow of any waterfall in the world, after Niagara, with an average rate of 1,746 m3/s.

5.Lake Baikal
Lake Baikal is the world's oldest and deepest lake at 30 million years old and with an average depth of 744.4 metres.
Located in the south of the Russian region of Siberia,it is the most voluminous freshwater lake in the world, containing roughly 20% of the world's (and 80 % of Russia) unfrozen surface fresh water.
At 1,642 metres, Lake Baikal is the deepest and among the clearest ( one can see fishes swimming at the depth of 18 metres) of all lakes in the world. 
Lake Baikal was formed as an ancient rift valley, having the typical long crescent shape with a surface area of 31,722 km2
The lake is completely surrounded by mountains. It contains 27 islands. The lake is fed by as many as three hundred and thirty inflowing rivers.It is drained through a single outlet, the Angara River.
Lake Baikal is rich in biodiversity. It hosts 1,085 species of plants and 1,550 species and varieties of animals.From total species of plants and animals 75% of them are not found in any other water body.
