Abstract
A method of dynamically switching partitions for a memory card having a plurality of physical blocks is provided. The method includes configuring logical blocks for mapping to at least a portion of the physical blocks and dividing the logical blocks into first and second partitions; coupling the memory card to a host system and setting CSD corresponding to the memory card as a first default value corresponding to the first partition, wherein the host system requests the CSD to obtain the first default value and accesses the first partition according to the first default value; and setting the CSD corresponding to the memory card as a second default value corresponding to the second partition in response to a switch command from the host system, wherein the host system re-requests the CSD to obtain the second default value and accesses the second partition according to the second default value.
