Abstract

An invention is provided for improving performance in block based non-volatile memory when performing random small write operations. When requests for small page updates are received for a memory page currently storing data, the updated page data is written to a reserve memory page. The reserve memory page can be in the same memory block as the target memory page, or in an associated reserve memory block. In addition, the associated logical page address is temporarily remapped to the reserve page. Later, when time permits, the page data for the block can be reorganized into continuous pages in a new block.
