Working Principles

AT28C256F-15PU utilizes a combination of electronic circuits and memory cells to store and retrieve digital information. It employs a floating-gate transistor structure that allows for non-volatile storage by trapping electrical charges. The memory cells are organized into an array, with each cell representing a bit of information. The address inputs select the desired memory location, and the control signals (CE, OE, WE) determine the type of operation (read or write) to be performed.
