Working Principles

The AT27C010L-45PC is based on the principle of electrically programmable read-only memory (EPROM). It utilizes a grid of transistors and floating-gate MOSFETs to store data. During programming, a high voltage is applied to the VPP pin, which enables electrons to tunnel onto the floating gate, altering the transistor's threshold voltage. This change determines whether the stored bit is interpreted as a logic 0 or 1 during read operations.
