Fast programming methods for flash memory devices

A page-programming method configured to program data of a page stored in a page register to a non-volatile memory array, comprising:

• executing a verify process, wherein the verify process comprises:
• reading the data of a selected byte in the page register and programming the data of the selected byte to memory cells corresponding to a selected column address in the non-volatile memory array;
• determining whether the data of the selected byte matches specific content;
• when the data of the selected byte does not match the specific content, updating an array column address according to the selected column address, reading data of the memory cells corresponding to the selected column address in the non-volatile memory array, comparing the data of the memory cells corresponding to the selected column address with the data of the selected byte to generate comparison data, and programming the comparison data back to the selected byte;
• when the data of the selected byte matches the specific content, not updating the array column address;
• and
• determining whether the selected column address is the last column address, and determining whether all the comparison data corresponding to the page matches the specific content when the selected column address is the last column address;
• and
• when any one of the comparison data does not match the specific content, executing a program process.
