Abstract:
In a method for storing data in a flash memory array, the flash memory array includes a plurality of physical pages. The method includes receiving a request to perform a data access operation through a communication bus. The request includes data and a logical page address. The method further includes allocating one or more physical pages of the flash memory array to perform the data access operation. The method further includes, based on a historical usage data of the flash memory array, selectively encoding the data contained in the logical page into the one or more physical pages.
