The storage transistor traps the electrons as it consists of the floating gate (floating gate is a transistor that can hold an electrical charge). There are two transistors in most of the cells: So now the storage will be in form of logic 1 or logic 0. These electrons are trapped inside a gate known as floating gate. The characteristics of a cell will be modified by the electrons.
Parallel built in eeprom is present in many microcontrollers. PARALLEL BUSįor total handling of memory it has a wide address bus and also a data bus consisting of 8 bits.

Some of the common types of serial interfacing are UNI/O, 1-wire, SPI, microwire and I2C. Address phase, data phase and op-code phase are the three phases in which this chip functions. There are two main categories of EEPROM devices: SERIAL BUS A basic ROM chip can only be programmed once whereas an EEPROM can be programmed again and again. We can also change the data in it according to our requirement, to erase a certain data we don’t have to erase the prom completely like in a regular rom. Data is created in them by electrical pulses and a grid. A SECURITY DOOR LOCK CIRCUIT using EEPROM EEPROMĮlectrically Erasable Programmable Read Only Memory (EEPROM pronounced as “double E prom) is like a ROM but data can be erased from it electrically without removing it from the computer.EEPROM INTERFACING WITH CONTROLLER in STEPS.INTERFACING OF AT24C02 EEPROM WITH 8051.EEPROM INTERFACING WITH MICROCONTROLLERS.
