Patent number: 6804150Abstract: A non-volatile integrated circuit NAND type flash memory device is provided that includes a select line driver and a slope control circuit. The select line driver supplies a string select line with a select voltage limited below a power supply voltage while a program voltage is supplied to a word line. The slope control circuit controls a rising slope of the program voltage such that a capacitive coupling does not arise between the string select line and a selected word line during a program operation. At this time, the select voltage that the select line driver supplies into the string select line is lower than the power supply voltage, and a difference between the select voltage and the power supply voltage is at least as much as a coupling voltage between the string select line and the selected word line. In addition, the program voltage that the slope control circuit supplies into the selected word line can be increased in a staircase form during the program operation.Type: GrantFiled: September 6, 2002Date of Patent: October 12, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-Hoon Park, Young-Ho Lim, Hyoung-Gon Kim
