ABSTRACT:
According to a method of controlling the operation of a flash memory device including a number of memory blocks, a memory block of the memory blocks is first selected as a reference block. A program operation is performed on a memory cell included in the reference block. In order to check an operating characteristic of the reference block, a threshold voltage level of the programmed memory cell is read. Parameters for performing an operation of the flash memory device are determined based on the operating characteristic of the reference block. The parameters are stored in the reference block.
