Working Principles

The AT93C56-10PI utilizes an electrically erasable programmable read-only memory (EEPROM) technology. It consists of a grid of memory cells that can be individually programmed or erased using electrical signals. Data is stored as charge within these cells, and the presence or absence of charge determines the binary value of each bit.

During read operations, the chip sequentially accesses memory locations and retrieves the stored data. Write operations involve sending appropriate signals to modify the desired memory cells. The chip's control logic manages these operations, ensuring accurate data storage and retrieval.
