Memory is an important component in the operation of various electronic devices. Considering the various needs of electronic devices, there are various types of memories, such as ROM, EPROM, EEPROM, SRAM and so on. M27C256B-12C1 is a EEPROM manufactured by STMicroelectronics, which integrates a large number of functions and is applicable to a wide range of fields. This paper will explain the application field and working principle of M27C256B-12C1.M27C256B-12C1 has the advantages of high speed, low power consumption, high integration, wide voltage range and high stability. Therefore, it can be widely used in smart cards, digital cameras, LCD display controllers and memory for a variety of communication products. For example, card products such as SIM cards and game cards also rely on M27C256B-12C1 as their storage medium. In addition, it can also be used in computer peripherals, such as the USB interface.As for the working principle, the memory of M27C256B-12C1 is formed by combining a large number of memory cells arranged in a certain order. Every single cell can store a bit of data. And each cell has its own complete set of circuit, related to the connection of write / read and address pins, clock and control signals, latch, erase and data transfer circuits, etc. The contents stored in the memory can be compared to the data stored in the same computer hard disk.In general, M27C256B-12C1 is an EEPROM integrated with perfect functions, strong stability and wide application field. Realizing the data storage in all kinds of electronic apparatus, its working principle is based on the basic elements of the memory cell, which circumscribes the whole operation of M27C256B-12C1 in a logical and understandable way.
