Working Principles

The AT27C1024-12PC is based on the principle of electrically programmable read-only memory (EPROM). It utilizes a floating-gate transistor structure to store data. During programming, a high voltage is applied to the gate of the transistor, causing charge to be trapped in the floating gate. This trapped charge determines the stored data. Once programmed, the data remains unchanged until the chip is replaced.
