Method and device for operating flash memory

The invention provides an operation method and device for a flash memory, and the operation method comprises the steps: writing an operation command into the flash memory when the data operation is carried out on the flash memory; the operation command at least comprises address information; the address information comprises a data address and a compensation characteristic value; the flash memory comprises a peripheral circuit and a memory cell array, the peripheral circuit adjusts a data operation parameter according to the compensation feature value and performs the data operation on the data at the data address in the memory cell array. When the data operation is performed on the flash memory, the compensation characteristic value is set in the address information, and a characteristic value setting sequence does not need to be additionally introduced, so that the data operation time of the flash memory is greatly saved, and the device performance is improved. 本发明提供了一种闪存存储器的操作方法及装置，操作方法包括：在对所述闪存存储器进行数据操作时，
