ABSTRACT:
A flash memory system includes a flash controller for controlling operation of at least two flash memory devices. A page buffer is allocated within each flash memory device, such that one page buffer functions as a designated target buffer and another page buffer functions as a mirror buffer. The flash controller transmits the page data to two flash memory devices simultaneously, such that no backup of the page data is required to be kept in the flash controller. Hence, there is no delay in writing the next page data from a host computer to the flash controller.
