The M29W400DB45ZE6E is a type of memory device. It is a high-density, electrically erasable programmable read-only memory (EEPROM) based on a non-volatile floating-gate technology. It provides efficient non-volatile read and write storage in a variety of applications.

Application Field

M29W400DB45ZE6E are ideally suited for printing, industrial and medical applications where data storage needs to be maintained in the event of power loss or device failure. For many applications, M29W400DB45ZE6E offer increased flexibility when compared to other non-volatile memory products, as data only needs to be written once and can then be viewed, altered and updated as needed. Its data retention characteristics also make this memory device well suited for communication systems, audio and video playback, solar tracking systems, computer-based control and instrumentation systems, set-top boxes and automotive applications.

Working Principle

Unlike EPROM, the M29W400DB45ZE6E does not require a high-voltage programming pulse to write data. Instead it requires a small voltage, of approximately 8 to 15V, to write data to the memory cell. This low-voltage requirement reduces power consumption and simplifies programming. The data cannot be read or written while a programming pulse is applied, thus ensuring the data is protected while programming is occurring. Once the programming pulse has ended, the internal control logic automatically checks the data, ensuring it has been written correctly.

M29W400DB45ZE6E feature an advanced verification algorithm which allows them to output a variable number of bits. This variable number feature provides flexibility in data storage and protects the data integrity of applications where error-correction coding is not available or desired. The device also offers power-on reset and self-timed write cycle operation, allowing data to be written even when power is turned off.

M29W400DB45ZE6E memory devices are available in both standard and high-endurance configurations. Standard endurance devices feature write-erase cycles of up to 10K and data retention of up to 10 years. High-endurance devices offer better performance, with erase-write cycles as high as 1 million and data retention of up to 100 years. This makes them ideal for applications requiring large amounts of data storage, such as data logging.

To ensure data integrity and reliability, they feature redundancy protection. This protection prevents corruption of data due to transient faults commonly encountered in systems subject to high noise or vibration. The memory device is also designed to operate in a wide temperature range and has a low power profile, making it well suited for low-power applications.

In summary, the M29W400DB45ZE6E is a highly reliable and efficient memory device with advanced features that make it suitable for a variety of applications. With its low-voltage programming requirement, advanced verification algorithm, and data redundancy protection, it provides efficient, non-volatile read and write storage for a variety of applications.
