What is there in a pendrive that stores data?

Question

In hard disks it is magnetic disks, etc...

Answer 1

Pen drives store data into flash memory.
Flash memory is a form of non-volatile memory that can be electrically erased and reprogrammed. Unlike EEPROM, it is erased and programmed in blocks consisting of multiple locations (in early flash the entire chip had to be erased at once). Flash memory costs far less than EEPROM and therefore has become the dominant technology wherever a significant amount of non-volatile, solid-state storage is needed. Examples of applications include digital audio players, digital cameras and mobile phones. Flash memory is also used in USB flash drives, which are used for general storage and transfer of data between computers. It has also gained some popularity in the gaming market, where low-cost fast-loading memory in the order of a few hundred megabytes is required, such as in Nintendo DS cartridges.

Flash memory stores information in an array of floating gate transistors, called "cells", each of which traditionally stores one bit of information. Newer flash memory devices, sometimes referred to as multi-level cell devices, can store more than 1 bit per cell, by varying the number of electrons placed on the floating gate of a cell.

Answer 2

Basically, A pen drive has two types of storage medium, Flash memory (Basically solid state memory chips similar to the RAM you use in your system) and Microdrives (Small mechanicaly driven disks) the most common being flash memory.

Answer 3

You need to read the article, copy/paste this into your browser -http://en.wikipedia.org/wiki/Flash_memory

If you do not trust the source, then go to wikipedia yourself and search for flash memory.
