Millipede is a type of non-volatile memory developed by IBM that stores data in nanoscopic pits burned into a thin polymer layer using MEMS probes. It promises a data density of over 1 terabyte per square inch and could replace hard drives. Unlike hard drives, which use a single head, Millipede uses thousands of nanoscopic heads that can read and write in parallel for better performance. Data is stored in a "dumb" medium using atomic force probes responsible for reading and writing large numbers of bits. Millipede has applications in micro drives and high capacity hard drives.

3. Promises a data density of more than 1Tb/sq. inch.

7. Uses numerous nanoscopic head which can read and write in parallel.

9. To position the pits according to the sillicon probes, the sled is moved in a X/Y scanning pattern.

11. Animated View:

13. In absence of a pit, the cooling is slower.

14. Electrical resistance is a function of changing temperature.

17. To write ‘1’ the tip is gently touches the surface causing a dent.

18. To erase the bit and return it to zero state, the tip is pulled up from surface.

23. Uses atomic force probes.

24. Data reads & writes in the storage field.

25. Data rate is 1Gb/s.
