Working Principles

The AT29C020-10JI utilizes flash memory technology to store and retrieve digital information. It employs a combination of floating-gate transistors and control circuitry to enable non-volatile storage. When data is written to the chip, the control circuitry applies a high voltage to the appropriate memory cells, trapping charge in the floating gates. This trapped charge represents the stored data. During read operations, the control circuitry senses the charge level in the memory cells and outputs the corresponding data.
