[0109] Example
[0110] In the storage management method of the NOR Flash of the small memory single-chip microcomputer in this embodiment, the small memory single-chip microcomputer integrates a NOR Flash chip. The NOR Flash chip includes a storage module and an execution program module. By constructing a sector mapping table, the execution program module is implemented in Storage management of writing data, reading data and space balance loss on the storage module; specifically:
[0111] 1) Initial management
[0112] Initialize the NOR Flash chip and build the sector mapping table;
[0113] 2) Write data management:
[0114] Enter the target logical address, retrieve the target physical address corresponding to the target logical address through the sector mapping table, and write the target data to be written and the data stored in the target physical address into the new physical address together, and at the same time, the target logical address The mapping relationship between t...
