Working Principles

The AT29C256-90TI utilizes Flash memory technology to store and retrieve digital information. It consists of a grid of memory cells, each capable of storing a single bit of data. These cells are organized into rows and columns, forming a matrix-like structure. When data is written to the memory, electrical charges are applied to specific cells, altering their state and storing the desired information. To read the stored data, the memory controller activates the appropriate row and column, allowing the data to be retrieved.
