    Abstract: A non-volatile memory management method and a non-volatile memory based apparatus are provided to reduce the erase count for extending use-by date of a flash memory in which a program/erase count is limited. A non-volatile memory management method comprises the following several steps. If a simple merge operation is performed, a log block does not have effective data anymore, namely becomes ineffective(110). An amount of vacant memory or the number of clean pages in the ineffective log block is detected(120). The detected number of clean pages is compared with a reference value(130). If the number of clean pages is larger than the reference value, the corresponding ineffective log block is allocated to a clean page start address, namely a reusable pool with a start address of a vacant space(140). If the number of clean pages is not larger than the reference value, the corresponding ineffective log block is allocated to a garbage pool(150).

    Abstract: PURPOSE: A page buffer management method and devices performing the same are provided to guarantee a validity of data. CONSTITUTION: A page buffer(50) stores LSB (Least Significant Bit) page data which will be a program on the page.

    Abstract: A method and a device for adjusting a memory capacity are provided to adjust a user usable memory capacity and a reserved memory capacity of the flash EEPROM according to a use state of the data storage device, thereby increasing lifetime of a flash EEPROM(Electronically Erasable Programmable ROM)-based storage device. A flash EEPROM(40) includes a user usable memory region(41) for storing user data and a reserved memory region(43) having at least one reserved block(45). A processor(30) stores a series of instructions, and reconfigures mapping information of the flash EEPROM representing the user usable memory region and the reserved memory region based on an inputted parameter when the instructions are executed in response to a capacity adjusting command. The parameter is a user usable memory region value, a reserved memory region value, a ratio between the user and reserved memory region values, or the number of reserved blocks. The processor includes an FTL(Flash Translation Layer) and the FTL reconfigures the mapping information of the flash EEPROM based on the inputted parameter.
