Abstract
An apparatus and method for managing flash memory based on recognition of patterns of write-target data are disclosed. A data analysis unit analyzes bit storage patterns that are stored in cells of the flash memory, and a data matching unit matches corresponding alternative patterns to the bit storage patterns based on the results of the analysis of the data analysis unit. According to the present invention, the reliability and durability of NAND flash memory can be improved because a minimum number of “0” bits are stored in a page. Furthermore, the application of the technology is easy and simple because a memory controller can perform management without changes in the structure and cell arrangement of a NAND flash device.
