Working Principles

The CAT25C128VI-GT3 chip utilizes an electrically erasable and programmable memory technology. It stores data in a grid of memory cells, each capable of holding one bit of information. The data can be written or erased by applying specific electrical signals through the chip's interface.

During a write operation, the desired data is sent serially to the chip, which then stores it in the appropriate memory cells. Reading data involves retrieving the stored information from the memory cells and transmitting it back through the chip's interface.
