Abstract:
1. A method for preventing read-disturb happened in a non-volatile memory, suitable for a non-volatile memory storage device, wherein the non-volatile memory comprises a plurality of physical blocks, each physical block comprises a plurality of pages, and the plurality of physical blocks are logically grouped into at least one data group, the method comprising: configuring a plurality of logical blocks for mapping the plurality of physical blocks of the at least one data group; storing program code executed by a controller of the non-volatile memory storage device for controlling the non-volatile memory storage device into at least one first block of the physical blocks, wherein the at least one first block is not belonging to the data group, and the at least one first block is not mapped to the logical blocks; and copying the program code stored in the at least one first block into at least one second block of the physical blocks when power is supplied to the non-volatile memory storage device, wherein the at least one second block is different from the at least one first block, the at least one second block is not belonging to the data group, and the at least one second block is not mapped to the logical blocks.
