IBM demonstrated the first integrated circuit memory block of said flash memory is expected to exceed

According to the United States, "Technology Review" magazine, IBM Corporation in Washington at the International Conference on electronic devices demonstrate the first integrated circuit memory block samples. This revolutionary new device combines computer storage capacity of traditional hard drives and flash-quick operation and durability characteristics. IBM said that the track density memory storage and manufacturing costs are expected to go beyond the flash.
IBM was first proposed in 2008 a "track" and the concept of computer memory, said memory circuit will replace the hard disk after 10 years. Integrated circuits responsible for memory read and write data storage components integrated in one chip, and after showing the various components of the memory circuit is located in a different place.
Track the information stored in memory nickel-iron alloy nano-metal online, different parts of nanowires by controlling the magnetic track to get the number 0 and 1. Nanowires of about 10 microns long and 150 nanometers wide, 20 nm thick, one end of each nanowire is connected with the circuit, which produces precise control of the electronic pulse used to write data to the electronic spin as a track within the nanowires. The top of the other end of the nanowires have other layers, so that track movement along the nanowires. Across the layer, a device that can detect track boundaries between reading out data.
New sample from the IBM labs in the Niuyueyueke City complementary metal oxide semiconductor (CMOS) manufacturing technology and are currently the scientific community in general to use the technology to manufacture semiconductor devices and a variety of processors. First proposed the concept of track memory and led the project, said Kim Stewart Tepa, which indicates that you can track memory for commercial production, but also need to be streamlined and improved.
Prospects of this technology depends largely on a single nanowire can be used to store a lot of very dense track data. Parkin said they are currently studying how to track as much as possible into a nanowire, the experimental results show that the nanowires made of different materials perform better.
The use of nickel-iron alloy sample is the so-called soft magnetic materials - are easily magnetized and the external magnetic field to the magnetization. Parkin team is testing the use of hard magnetic materials, hard magnetic materials is not easy to magnetization, and more little harder, be more easy to put a lot of tracks in the nanowires.
From the drum, tape to disk, the computer has been inseparable from the head to read and write 0 and 1. However, technology is fast, less than 20 years ago, CD-ROM drive of the territory invaded; less than 10 years ago, U disk to a floppy disk and floppy drive out of the arena. Today, large-capacity disk and memory fast, lightweight and durable as one, and finally put a magnetic device ruthless. A bunch of hard drive technology with IBM's patent did not stop the pace of technological revolution. "Enterprise is the main innovation" was at IBM who has been fully reflected.
