IBM MILLIPEDE

CONTENTS IBM Millipede ? Capacity Basic concepts Reading and Writing data Current state of the art Ongoing developments

MILLIPEDE Non-volatile computer memory A nanotechnology based approach

to data storage Developed by IBM The name “Millipede”

FEATURES Storage capacity – 1 Tb / sq inch Equal to 25 DVD 25 billion texts in a stamp sized

surface Enable 10Gb of storage in cell

phones Highly reliable

BASIC CONCEPTS Modern computers – DRAM

technology Hard drives – metal disc with

magnetic material Millipede uses a “dumb” in an

electronic medium Uses many nanoscopic heads So high throughput

Uses atomic force probes Data reads & writes in the storage

field Access time is small Data rate is 1Gb/s Needs less power about 100mw

Reading & Writing data Stores & reads data thermo-

dynamically To read Probe is heated at 300

degree To write Probe is heated above glass

transition temperature

Areal Density

DRAM - 10Gb/ sq inch Flash ram - 25Gb/ sq inch Hard drives - 250Gb/ sq inch Millipede – 1Tb/ sq inch

Applications

Can be used for micro drives Enabling use in small foot print

devices watches, mobile phones and personal media systems

Current state of the art

Earlier – 32*32 grid with 3*3 sled Now – 64*64 grid with 7*7 sled Multiple rewriting Bit level erasing is not allowed

Ongoing Developments

Preparing high capacity data drives

Can hold 600,000 digital images Trying to increase the number of

layers Researching to reduce the cost Bit stability investigations
