Working Principles

The AT28C17-15SC utilizes a combination of electrically erasable and programmable read-only memory technologies. It stores data by trapping electrical charges within its memory cells. The stored data can be accessed and modified through appropriate control signals.

During write operations, the desired data is applied to the data inputs (DQ0-DQ7) and the corresponding address is provided through the address inputs (A0-A10). The Write Enable (WE) pin is activated to initiate the programming process, which modifies the memory cells accordingly.

For read operations, the address is provided, and the Chip Enable (CE) and Output Enable (OE) pins are activated. This allows the data stored at the specified address to be read from the memory.
