The flash memory system includes a flash memory controller and flash memory cells. The flash memory controller includes a buffer register for caching a word line of data. A write unit writes data to the flash memory using the buffer register by receiving data to be written to said flash memory, storing the data in the buffer register; and writing all data within the buffer register, in parallel, into the flash memory. A write verify unit of the flash memory controller reads data written to the flash memory, compares the data to corresponding data of the buffer register, and determines whether the data read from the flash memory is the same as the corresponding data of the buffer register. A read unit reads data from the flash memory using the buffer register by receiving an address location to be read from said flash memory, determining whether the address location is among addresses of data already stored in the buffer register. If so, the read unit reads data from the buffer register corresponding to the address location. If not, the read unit retrieves data from the flash memory cells containing the address location and then reads the data from the buffer register. By providing a word line buffer register in connection with the flash memory, overall system response time is improved. Method and apparatus embodiments are provided. |
