Abstract: A mass storage memory system and a method for re-allocating memory partition space is provided. The storage system includes a memory controller with a microprocessor that is adapted to receive data via a logical interface from a host system; a first memory partition with a system area and a data area; and a second memory partition with a system area and a data area; wherein the memory controller re-allocates memory space from the second memory partition to the first memory partition that is either full or has reached a threshold value, by using a virtual block address for the system area and the data area such that the system area and the data area appear contiguous to the host system.

Abstract: Techniques for managing data in a non-volatile memory system (e.g., Flash Memory) are disclosed. A controller can use information relating to a host's filing system, which is stored by the host on non-volatile memory, to determine if one or more clusters (or sectors with clusters) are currently allocated. The controller can use the information relating to the host's filing system to ensure that one or more clusters (or one or more sectors within a cluster) are not copied from one location to another location in the memory during a garbage collection cycle. As a result, some unnecessary operations (e.g., copying data) which are conventionally performed can be avoided and system performance can be enhanced.
