Abstract: A method, apparatus, and computer program product are provided for enhancing memory erase functionality. An apparatus may include a processor configured to initiate, at a slave device comprising a block-based mass memory, a memory management session with a host device in communication with the slave device such that the host device has ability to read from and write to the mass memory. The processor may be further configured to track changes made by the host device to memory allocation data stored on a memory block within the mass memory. The processor may additionally be configured to determine based at least in part upon the tracked changes whether the host device marked any memory blocks as free. The processor may be further configured to erase one or more memory blocks determined to be marked as free. Corresponding methods and computer program products are also provided.

Abstract: A method, apparatus, and computer program product are provided for enhancing memory erase functionality. An apparatus may include a block-based mass memory and a controller configured to receive an erase command from a host device comprising an indication of a location of a block in the mass memory storing memory allocation data. The controller may be further configured to access the memory allocation data based at least in part upon the indicated location. The controller may additionally be configured to determine, based at least in part upon the memory allocation data, blocks within the mass memory that have been freed by the host device. The controller may also be configured to erase the freed blocks. Corresponding methods and computer program products are also provided.
