    • A method for memory space management is disclosed. It uses a resident program loaded into an operation system or the controller of a storage device to monitor the storage space and the resource allocation of the file system of the storage device. The status of the logical address with an erased and invalid data mapped with a physical block is checked via a L2P mapping table. By using a data erase instruction, the controller modifies the L2P mapping table to cancel the link relation between the physical block and the logical address and erase the physical block to release the memory space. Finally, the check location is stored for a next check. The method for memory space management improves the access speed and the usage life of the storage device.
    • 公开了一种用于存储器空间管理的方法。 它使用加载到操作系统中的驻留程序或存储设备的控制器来监视存储设备的文件系统的存储空间和资源分配。 通过L2P映射表检查具有与物理块映射的擦除和无效数据的逻辑地址的状态。 通过使用数据擦除指令,控制器修改L2P映射表以消除物理块和逻辑地址之间的链路关系,并擦除物理块以释放存储器空间。 最后,检查位置被存储用于下一次检查。 存储空间管理方法提高了存储设备的访问速度和使用寿命。

    • A non-volatile memory storage device with functions of boosting supply voltage and signal level can adopt a non-volatile memory having an operating voltage higher than the supply voltage provided by the host device as a storage medium. The non-volatile memory storage device includes a supply voltage booster, a non-volatile memory storage unit and a controller. The supply voltage booster boosts the lower supply voltage provided by the host device up to the higher operating voltage of the non-volatile memory. The controller adjusts the interface signal to a proper interface signal level by cooperating with the supply voltage and the operating voltage so as to avoid the interface from damage owing to an over high signal level or avoid the non-volatile memory unit from not correctly receiving signal due to an over low signal level.

    • An electronic storage device (320) for connecting with a host system (100) includes a storage unit (360) including at least one memory segment which has at least one physical block, a memory unit (350) receiving access commands sent from the host system, and a control unit (340) connecting with said memory unit. Each of the access commands contains at least a logical address which corresponds to a physical block. The control unit determines the command execution order of the access commands according to adjacent extent of the physical blocks in said memory segment to which the logical addresses of said access commands correspond. A control method of the electronic storage device is also disclosed in the present invention.
