Abstract
A portable data storage device includes a first storage unit having a data storing zone and a reserved zone for bad blocks in the first storage unit, and a second storage unit having a look-up table. The look-up table lists a number of configuration modes for the portable data storage device, each defining specific allocation sizes for the reserved zone and the data storing zone. The portable data storage device is configured to use a kth configuration mode. A method for dynamic memory management includes: i) determining a number of the bad blocks assigned to the reserved zone; ii) with reference to the look-up table, determining if this number is greater than a limit associated with the kth configuration mode; and iii) if so, reconfiguring the portable data storage device to use a (k+1)th configuration mode.
