EEPROM (Electric Erasable Programmable Read Memory - only).
EEPROM stands for. Read - Only Memory Erasable Programmable Power is a kind of non-volatile EEPROM memory in computers or other electronic devices used to collect data when the power is turned off to protect. But in case SRAM or DRAM data lost To go when the device is turned off. Many types of data to store special EEPROM with flash memory, known as the more economical in comparison to EEPROM devices.
History: -.
In1983, George Perlegos development. Intel in 2816, is Intel prior EEPROM technology. But now we are using thin gate oxide, because it can remove the chip itself. Bit purple without special. George Perlegos and others left to form Seeq Technology, the heat pumps cost of providing the necessary Pressure for EEPROMs.
EEPROM: -.
There are two ways. EEPROM.
1 Parallel 2 Serial Bus Bus.
Parallel Bus: -.
Parallel EEPROM devices are often vehicles are wide enough on the integrity and the cover 8-bit data bus chip select devices most. (CS) and write protect pin (WR), some microcontrollers. Parallel EEPROM
The operation of the EEPROM. Parallel is easy and fast compared with serial EEPROM, but these devices are great because of the lower leg (28 legs) and has reduced his popularity. serial EEPROM or Flash.
Parallel EEPROMs use of such programs. POS terminals, industrial control adapter. LAN, Switches, Telecommunications, mobile phones and modems.
Serial Bus: -.
Serial EEPROM work in three modes. : Phase OP - Code, data and address bus Phase.The OP - Code is entered. The first 8-bit serial EEPROM PIN entry device, followed by. 24/08 bit depth based on data from the device based read or write.
Serial EEPROM products to use the lot used to store user. reconfigurable. Program is a common drive. Modems, cellular phones, VCRs, CD players, listen AIDS PCMCIA card, mobile phones, computers, laser printers, and pagers.
The Comparison with EPROM and EEPROM /. Flash: -.
EPROMs can not delete a program on electricity and hot carrier injection into floating gate. Remove as possible with the help of light sources. Ultra Violet, although in many ways, EPROMs plastic sheet opaque to light. Ultra Violet, and "One" program.
EEPROM can be programmed. And usually by the emission electric field in the industry as "Fowler removes known. - Nordheim tunneling.
Most of the NOR flash memory is handed a form of hybrid programming. Hot carrier injection and removed with the help of Fowler - Nordheim tunneling.

Can I upgrade. s' memory of my laptop.
Here are brief me on my laptop. Toshiba Satellite M35X Series Latop system specifications RAM types.

PC6400, PC5300, PC4200, I can upgrade the memory of my laptop. Thank you.
No, you can not. More memory you have is compatible with PC6400, PC 5300, PC4200 will not work because the socket you have on your computer. PC2700 obvious that they are not compatible. Memory will not fit in the slot. You get a different memory types are compatible with the connector on the computer. But of course you can not use the current one.
