摘要： A method is employed to manage a memory, e.g., a flash memory, including a plurality of paired pages. Each paired page includes a page and a respective risk zone. For each write command, at least one unwritten page is selected for writing new data. For each unwritten page whose risk zone includes at least one written page, each written page is copied or backed up, and the new data is written to the unwritten page. For each unwritten page whose risk zone lacks a written page, the new data is written to the unwritten page. In an embodiment, the written page is copied only if the unwritten page and the written page are operated by different write commands.

摘要： A method for copying data in a non-volatile memory system is disclosed. The method includes calculating a number of errors of a first set of data from a source block of the non-volatile memory saved in the buffer of the controller, transmitting the first set of data saved in the buffer of the controller to a buffer of the non-volatile memory when the number of errors is lower than a threshold, and programming a destination block of the non-volatile memory with the first set of data saved in the buffer of the non-volatile memory when the number of errors is lower than the threshold.

摘要： A non-volatile memory device, and a method for accessing the non-volatile memory device are provided. The non-volatile memory device is connected to a host via a bus. The non-volatile memory device comprises an MCU. By independently processing the particular commands using only the auxiliary circuit, the MCU can cease to operate, thus saving power. By setting the bus into power saving mode when the non-volatile memory device is busy, the host and the non-volatile memory device would not communicate mutually, thus, saving power.

摘要： According to the method of wear leveling for a non-volatile memory of the present invention, the non-volatile memory is divided into a plurality of windows, and a mapping table is built in which the logical block addresses having frequently accessed data are allocated equally to the plurality of windows. The logical block addresses may store a File Allocation Table (FAT) or a directory table; therefore the windows they locate will be written or erased more frequently. In an embodiment, the logical block addresses having frequently accessed data are allocated on a one-to-one basis to the plurality of windows. For example, the plurality of windows may comprise Windows 0, 1, 2 and 3, the logical block addresses comprise logical block addresses 0, 1, 2 and 3, and logical block addresses 0, 1, 2 and 3 point to Windows 0, 1, 2 and 3, respectively.

摘要： A hierarchical mechanism for preventing concentrated wear on single physical block or a specific set of physical blocks in the physical memory is proposed. The logical blocks mapping to the physical blocks in the physical memory are classified into two different levels for implicitly representing the modification times of the physical blocks. A modify count and a maximum modify count are further included for counting the modification times in a single process of the hierarchical mechanism and for limiting the modification times in single process, leading to the probabilities of all the physical blocks being modified in the physical memory being balanced. The breakdown of the physical memory caused by the breakdown of a specific set of physical blocks or single physical block is thus prevented.

摘要： A non-volatile memory storage device has a non-volatile memory, e.g., a flash memory, and a controller coupled to the non-volatile memory. The controller comprises a plurality of control circuits and an arbitration circuit. Each control circuit is configured to generate a request to update the chip-enable (CE) signals for non-volatile memory, and the arbitration circuit is configured to determine when the requests are acknowledged. The arbitration circuit generates acknowledge signals to the control circuits when all of the requests of the control circuits have been received by the arbitration circuit. The CE signals for non-volatile memory are updated when requests are acknowledged.
