Working Principles

The M27C4002-10F6 is based on the principle of electrically programmable read-only memory (EPROM). It utilizes a grid of transistors to store binary data in the form of electrical charges. These charges represent the "1" or "0" states of each memory cell. The chip can be programmed by applying specific voltages to the programming pins, which alter the charge distribution within the memory cells. Once programmed, the data remains stored until it is erased using
