Working Principle of Flash Memory

Flash memory is a non-volatile type of memory that utilizes electronic instead of mechanical parts. It uses a floating gate to store data. The electrons are stored in the floating gate and can remain in this state for long period of time without any power supply. To read or write data from the memory, the current must be passed through the gate and the electrons can be transferred between the gate and the source/drain. The electrons are transferred in two ways, programming and erasing.

Programming Memory

Programming is used to write data into the memory. A high voltage is applied to the source and the drain which forces electrons to move through the gate and store the data. This data remains stored until the device is powered off and the electrons remain in their place.

Erasing Memory

Erasing is used to delete data from the memory. A high voltage is applied to the control gate which forces electrons to move out of the gate. This is done by inducing a strong electric field at the gate so that the electrons are repelled out of the gate. The data written in the memory is then erased from the memory.

Conclusion

The M29F400BB55N1 Flash memory is a reliable memory device with a wide range of applications. It offers a number of features including high speed, advanced security, low power consumption and a wide range of clock rate adjustment.
