A method and system for identifying a NAND-Flash without reading a device ID. The method includes: executing an identification flow for setting a first page of a block as a target block, utilizing a combinations table to query a target block, evaluating a result by comparing a identifying information in the target block with the combinations table, trying all combinations in the combinations table until correctly identifying the NAND-Flash by having a positive match result or returning an error if none of the combinations match.

Task management methods. A plurality of GBL (global bandwidth limiter) classes is provided. One of the GBL classes is selected based on the priority of a first task, in which the first task is from a MCU (micro-controller unit) bus. A system GBL class is selected based on the highest GBL class which has been selected among the GBL classes. A bandwidth limiter of a DMA (direct memory access) unit is assigned according to the system GBL class and the priority of a second task if the DMA unit is activated by the second task. The second task is from a DMA bus, and the cycle between the DMA and MCU buses is determined according to the bandwidth limiter.
