Memory - MX29GL128FLT2I-90G application field and working principle

MX29GL128FLT2I-90G is a 256M-bit Flash Memory from Macronix which is listed as part of their MXSMIO family. The memory device is a single side chip with multiple cells, accessed by Flash commands and with a double data rate of 80MHz. It can work in several different application fields, ranging from storing data in a fixed format or from dynamic data displaying to updating registry information or to access quickly to frequently updated data.

The working principle of MX29GL128FLT2I-90G lies in the Flash Memory Structure. The technology behind Flash Memories, also known as Non-Volatile Memories (NVM), came to the surface in the early 90s and had quickly become the standard technology for storing information in terms of both performance and cost. It is essentially based on one-time programming a non-volatile memory element by applying an appropriate voltage. This makes it much more reliable than traditional memories that are based on EEPROMs.

The MX29GL128FLT2I-90G is composed of several memory cells, each with two circuit elements: an isolated poly-silicon floating gate and a select transistor gate. They are used for storing the data. The poly-silicon gate is responsible for storing the information, while the select transistor that is equipped with the gate controls the data flow. In addition, the memory also has a built-in ECC control unit (ECC) which can detect and correct most of the errors.

The main application fields of MX29GL128FLT2I-90G can be summarized as:

• Fixed Format Data Storage – MX29GL128FLT2I-90G can be used to store data in a specified format, such as protocols, configuration data, passwords, passwords hashes and other information in a non-volatile way;
• Dynamic Data Display – The data stored in the MX29GL128FLT2I-90G can be retrieved very quickly and is highly reliable, making it ideal for applications such as GPS navigation systems, digital camera, digital picture frames, portable media devices and other dynamic data displays;
• Registry Update – Due to its high speed, MX29GL128FLT2I-90G can be used to store frequently updated registry information, such as user profiles, setting up data and product catalogs.

In conclusion, the MX29GL128FLT2I-90G Flash Memory from Macronix is extremely reliable and can be used for a wide range of applications. Its advanced Flash Memory technology provides a robust solution for storing and accessing data quickly and reliably.
