Technical Field

The embodiment of the invention relates to the technical field of data storage, in particular to a data storage method and device of a memory, electronic equipment and a storage medium.

Background

The floating gate field effect transistor in the memory is structured by additionally arranging a floating gate between an original gate and a silicon substrate, and when a certain voltage is applied to the original gate (namely a control gate), a large amount of electrons in a drain can pass through the substrate and penetrate through a tunneling oxide layer to reach the floating gate. However, a part of electrons will remain in the tunnel oxide layer during the process of passing a large amount of electrons through the tunnel oxide layer, so that during the subsequent data reading process, the electrons remaining in the tunnel oxide layer in the floating gate field effect transistor in the unselected word line may be sucked into the floating gate, resulting in the threshold of the floating gate field effect transistor being raised.

In the process of debugging a program, a user may slightly modify a certain statement in the program many times, and thus, a situation may occur in which data writing and erasing operations are repeatedly performed on one block in a memory for storing the program. As the number of data writing and erasing operations increases, the probability that some word lines in the block are repeatedly written and erased increases because the difference between the data written in the previous and subsequent times is small. Therefore, the more electrons are stored in the tunnel oxide layer of the floating gate field effect transistor in the word lines, so that when the word lines are used as non-selected word lines in a data reading operation, the more electrons are more easily absorbed into the floating gate in the tunnel oxide layer of the floating gate field effect transistor in the word lines, the threshold value of the floating gate field effect transistor is raised, and the reliability of stored data is affected.
