Flash Drives A common property of mass storage systems based on magnetic or optic technology is that physical motion‚ such as spinning disks‚ moving read/write heads‚ and aiming laser beams‚ is required to store and retrieve data. This means that data storage and retrieval is slow compared to the speed of electronic circuitry. Flash memory technology has the potential of alleviating this drawback. In a flash memory system‚ bits are stored by sending electronic signals directly to the storage medium

A. VOLATILE MEMORY Volatile memory‚ also known as volatile storage‚ is computer memory that requires power to maintain the stored information‚ unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as term Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge‚ the information eventually fades unless the capacitor

ABSTRACT A conducting plastic has been used to create a new memory technology which has the potential to store a mega bit of data in a millimeter- square device-10 times denser than current magnetic memories. This device is cheap and fast‚ but cannot be rewritten‚ so would only be suitable for permanent storage. The device sandwiches a blob of a conducting polymer called PEDOT and a silicon diode between perpendicular wires. The key to the new technology was discovered by

CMOS Memory Complementary Metal Oxide Semiconductor (CMOS) is a transistor that combines both positive and negative channel in the same circuit‚ and consume lower amounts of power when compare with single polarity devices. In 1963 C. T. Sah and Frank Wanlass prove that combining both channels in a circuit drew close to zero power in standby mode. RCA laboratories first produce CMOS technology for aerospace and commercial applications. The first static RAM was introduced in 1968 with

1 Memory Basics Memory is the workspace for the computers processor. It is a temporary storage area where the programs and data being operated on by the processor must reside. Memory storage is considered temporary because the data and programs will remain there only as long as the computer has electrical power or is not reset. Before being shut down or reset‚ any data that has been changed should be saved to a more permanent storage device of some type (usually a hard disk) so it can

Top 10 Credit Card Flash Drive Models to Choose From: Part-1: What are a Credit Card Flash Drive Model and What is it used for? Everyone loves making a statement when it comes to the professional industry. Imagine being in a conference where you wish to handover your business details to someone you have just met. Gone are the days when people merely shared their location or names. People today like sharing work samples along with their business credentials. This has led to the development of Credit

Computer Memory Basics Although memory is technically any form of electronic storage‚ it is used most often to identify fast‚ temporary forms of storage. If your computer’s CPU had to constantly access the hard drive to retrieve every piece of data it needs‚ it would operate very slowly. When the information is kept in memory‚ the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above‚ the CPU accesses memory according

Storage Devices & Memory Videos 1.06 and 1.08 covered Storage Devices and Memory. The 1st one covered all the different types of storage devices. It started with hard drives and went on to floppy drives‚ cd’s‚ dvd’s‚ solid state removable and tape drives. It also covered all the interfaces that can be used with them. The video also touched on power connections used to power up the different storage devices. Video 1.08 covered memory. It went through the two different types of memory which are ROM

A USB (“universal serial bus”) flash drive is a small‚ portable‚ external flash drive that plugs into a computer’s USB port. Like hard disks‚ USB flash drives store information‚ but they more easily transfer that information from one device to another. A USB flash drive has three basic components – the board‚ the NAND flash memory storage chip‚ and the controller chip. The board holds all of the internal components and includes the USB connector. The flash drive uses the board as a means of transferring

Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. Semi conductors consist of array of transistors with each transistor being a simple switch between electrical 0 and 1. Now often bundled together in there 10’s of millions they form highly complex‚ intelligent
