Abstract
A memory controller for controlling a flash memory is provided. The memory controller includes a control circuit and a voltage generator. The control circuit is configured to program one or more pages of the flash memory in sequence, wherein each page includes a plurality of bytes. The voltage generator is configured to adjust the output voltage according to the control signal from the control circuit. The control circuit performs a programming verification operation on each byte of a current page of the one or more pages in a page programming mode, and calculates the first number of bytes which fail the programming verification operation and performs a programming operation again. The control circuit determines the programming mode of the page after the current page as the page programming mode or the byte programming mode according to the first number.
