Working Principles

The M27C2001-70C6 utilizes a floating-gate transistor structure to store data. During programming, a high voltage is applied to the specific address lines and the corresponding data lines, causing charge to be trapped in the floating gate. This trapped charge alters the transistor's threshold voltage, effectively storing the desired data. During normal operation, the chip reads the stored data by applying appropriate voltages to the address and control lines, allowing the information to be accessed through
