One of the first solid-state devices was a crystal radio. In a crystal radio, a piece of wire positioned on a crystal's surface is able to separate the lower-frequency audio from the higher-frequency transmitted radio carrier wave. This form of signal detection is due to the crystal's ability to pass a current in only one direction.http://electronics.howstuffworks.com/radio.htm
“Solid-state gets its name from the path that electrical signals take through solid pieces of semi-conductor material.”
Before semi-conductors the use of vacuumed tubes was the alternative.
Vacuumed Tubes where large and generated large amounts of heat.

In an odd way of thinking, I am glad we had to do the power point thing. Thanks to all of the presentations conducted, I have a newer appreciation and understanding of the impact of solid state devices in our common lives,and especially for the future of Solid State Technology.
Thanks Classmates
Flash memory comes in two types NAND and NOR. Named “flash” for how fast it can be erased. NOR flash and NAND flash refers to the type of logic gate used in each of the storage cell systems. Nor is fast low density memory. NOR flash has typically been used for code storage and direct execution in cell phones and PDAs.(mostly read only) NAND flash has been primarily used as a high-density storage for cameras and usb drives. NAND has a lower cost-per-bit of stored data. All types of flash memory erode after a certain number of erase functions ranging from 100,000 to 1,000,000.

A solid-state device is an electronic or hardware device built entirely from solid materials and contains no moving parts. The transistor is considered to be the first widely used solid-state device and is still used in most electronic devices today.Flash memory uses a type of EEPROM which stands for Electrically Erasable Programmable Read-Only Memory and is a non-volatile form of memory. It is used when data needs to be stored but the power to the device must be turned off.Flash memory is a type of solid-state device that comes in many forms.
Computer’s BIOS chip
CompactFlash often found in digital cameras
SmartMedia also found in digital cameras
Memory Stick also found in digital cameras
PCMCIA (personal Computer Memory Card International Association) Type I, II, and III used in solid-state disks in laptops
Memory cards in video game consoles.
USB thumb or pin drive
Flash memory consists of a grid of columns and rows with a cell that has 2 transistors at each intersection. The 2 transistors are separated by a thin oxide layer. One of the transistors is called a floating gate and the other a control gate. Flash memory ranges in size from 8Mb up to 512GB and vary in price depending on manufacturer and size, both physical and memory.They are typically used in digital cameras, camcorders, cell phones.Memory cards come in a variety of types:
Secure Digital (SD)
CompactFlash (CF) type I and II
Memory Stick (MS)
MultiMediaCard (MMC)
xD-Picture Card (xD) and
SmartMedia (SM)
These cards are physically different and not interchangeable.Another form of flash memory is the Universal Serial Bus (USB) memory stick. It is a flash drive as it uses flash memory to store its data on the device. The small printed circuit board that carries the circuit elements and USB connector are insulated and protected inside a case. A USB flash drive is also called a thumb drive or a pin drive.They can vary in size, both in memory and in physical size. They come in a variety of styles and can be incorporated into pens, bracelets, watches.

History of television remote control. First remote was developed by Zenith Radio Corporation. In 1950 the “Lazy Bone” was a wired remote that could turn off and on, and change channels. Consumers did not like do to the tripping hazard of the wire. Next was the Flash-matic. Developed by Zenith engineer Eugene Polley. First wireless TV remote in 1955. It operated by four photocells which were placed one in each corner of the TV screen. This would turn on and off the TV, sound on and off and turn the channel tuner dial clockwise and counter clock wise. The main problem was that on sunny days the sunrays would change the channel.
Introduced in 1965, Designed by Doctor Robert Adler, a Zenith engineer. This was designed for use with color televisions receivers and used until 1972 model year. This space Commander 600 had an additional feature that set it apart from all other remotes. This remote could adjust color hues. This was adjusted by pressing the mute button on the remote, a relay would be activated in the TV in which to transfer the VFH motor drive tuner circuit to motorized hue control. This would allow the user to adjust the hue in increments by depressing the channel up or down buttons on the remote control and would restore the TV to normal tuning operation when the mute button was pressed again. The Space Commander 600 was transistor operated. This brought the price down on remote controls and in size as well. Until now, may I present you with the Jumbo Remote!!!!

Solid state devices are the future of storage for anyone who wants to have an electronic. The solid state hard drive has no moving parts but cost about as much as the price tea in china. The sold state drives use solid pieces of semi-conductor material placed on an circuit board and when electrical signals are applyed you get the ability for faster response and safer storage. I found my information via the Intel Website.
Solid State Drive is a Data storage device that uses solid state memory to store persistent data with the intention of providing access in the same manner of traditional block I/O Hard disk drive. Flash memory is known as a solid state storage device which means there are no moving parts. Flash memory is a type of EEPROM chip which stand for Electronically Erasable Programmable Read only Memory.
Here are a few example of Flash memory
BIOS chip in your computer
Compact Flash
Smart Media
Memory Sticks
PCMCIA Type I Type II memory card
Memory card for video games
There are some obvious advantages over a standard mechanical hard drive. Solid state there are no moving parts no spinning platter, no actuator arm and no motor just a bank of memory chips. there is a much higher degree of mechanical reliability because they are just a bank of chips. no time used to spin up the hard drive it is just up and ready as soon as it is powered. read much faster because there is no time spends for the actuator arm to read information off the platter. no noise generated by the solid state because there is no spinning motor. file fragmentation have very little impact on solid state drive because the very constant seek time performance of this type of drive. withstand shock and temperature extremes better than mechanical drive. Wear out. After a while the individual bits will wear out to the point it can’t be erased or written to again. Limited number of time information can be written on to a location (a BIT) this will limit the life time of the solid state drive to one year to five years with regular or normal use. MLC type of solid state drive tends to be slower and have really long write times. It’s even slower that standard hard drive and are not usually recommended for using a primary drive with an operating system installed. SLC Type is faster than MLC but more expensive Even the cheapest MLC type base solid state drive will be more expensive than an equivalent size mechanical drive. Difference on memory capacity. Solid state drive does not have the capacity of mechanical drive. This means that you would pay the same price for a 32GB solid state drive and a 320GB mechanical drive.

Solid-state gets its name from the path that electrical signals take through solid pieces of semi-conductor material. Before solid-state devices, electricity passed through the various elements inside of a heated vacuum tube. Solid-state devices, such as a transistor, use conductors to control the flow of signals through a circuit.
They have no mechanical or moving parts giving them many advantages such as no malfunctions or parts, low next to none heat emission, silent, have lower access time and latency.
Solid state devices have replace vaccuum tubes in about almost every electronic device. One of the first solid state devices was the crystal radio.

Solid state data storage is extremely fast. It completely exhudes seek times, as the medium has no mobing parts. The most common solid state controller, being a form of flash memory, uses floating gate transistors to stores its data. Sadly, most devices have finite read/write limitations. However through read/write balancing, and keeping each virtual sector at about the same number of read/write cycles, the typical user will not reach the drives' lifetime limitations prior to its' storage space becoming obsolete and insignificant.

The Laserdisc is an analog video disc that was first released for the consumers in 1978. The first movie comercially released was "Jaws." The Laserdisc was also famous for "Dragon's Lair." The discs are a size of vinyl records, usually double-sided, and contained at least 4 discs for a movie. The main downfall of Laserdisc was the cost of the players, costing about $2000.

A solid-state drive (SSD), sometimes called a solid-state disk or electronic disk, is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. They are opposite from the magnecit disc normally found in the other drives that are available.

one of the solid state device is USB flash drive. it stores alot of data and removable and rewritable. some allow up to 100,000 write/erase cycles and used the same purpose from floppy disk or CD's. they are smaller, faster, alot of capacity and more durable. it's used electrical power from the computer and stores information on the chip.
