Abstract:
A flash memory control technology with high efficiency, which records a logical page table in a random access memory. The logical pages that have been collected from a data-interspersed block into a destination block of a flash memory are recorded in the logical page table. Without accessing a logical-to-physical address mapping table stored in the flash memory, the physical pages in the data-interspersed block corresponding to the logical pages recorded in the logical page table are regarded as containing invalid data.
