Advantages and Disadvantages

Advantages

• Large storage capacity
• Fast access time
• Low power consumption
• Reliable data retention

Disadvantages

• Limited write capability: The M27C2001-12F1 can only be programmed a limited number of times before it becomes unreliable.
• Lack of flexibility: Once programmed, the data stored in this PROM chip cannot be easily modified or erased.

Working Principles

The M27C2001-12F1 operates based on the principle of electrical charge trapping. When data is programmed into the chip, charges are trapped in specific memory cells, representing the stored information. During read operations, these charges are detected and converted into digital signals, allowing the retrieval of the stored data.
