Working Principles

AT27BV256-12JC utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It stores information in a grid of memory cells, with each cell capable of holding one bit of data. The memory cells are organized into rows and columns, and data can be read from or written to specific memory locations using address inputs. The chip enable (CE), output enable (OE), and write enable (WE) pins control the operations of reading, writing, and erasing data.
