NONVOLATILE SEMICONDUCTOR MEMORY DEVICES AND PROGRAM METHOD THEREOF

摘要

A nonvolatile semiconductor memory devices and program method thereof is provided to improve program speed by omitting pass / fail inspection section to a certain program loop. In programming a flash memory, a memory cell is programmed through repeat program loop and some of the program loops are composed of program running and verification reading section and the others are composed of program running, verification reading, determination section. Some of the program loops includes discrimination section at first program loop selectively.
