Patent number: 6707714Abstract: A memory cell array of a NAND-type flash memory is divided into a first and second cell arrays, and, during a read operation, a first voltage is applied to non-selected word lines of the first cell array, and a second voltage lower than the first voltage is applied, to non-selected word lines of the second cell array. The first cell array has a comparatively large write operation frequency, and therefore readily assumes an over-programmed state as a result of repeated write operations, whereas the second cell array has a comparatively small write operation frequency, and it is therefore difficult for same to assume an over-programmed state. As a result, the first voltage is made high, such that read problems are avoided even if over-programming arises, and the second voltage is made low, such that a read disturb is suppressed and a data change is avoided.Type: GrantFiled: October 22, 2002Date of Patent: March 16, 2004Assignee: Fujitsu LimitedInventor: Shoichi Kawamura

Patent number: 6704242Abstract: An input part and a feedback part are arranged in series between a second power supply line and input nodes of inverting circuits. The input part connects the second power supply line to one of the input nodes of the inverting circuits in accordance with an input signal. One of the inverting circuits operates so that a logical value corresponding to the input signal is latched into a latching part. The feedback part connects only one of the input nodes to the input part in accordance with an output level of the latching part, thereby fixing the latching state of the latching part. Since the number of stages of circuits from the input part to the latching part can be reduced, the input signal can be latched reliably even when the power supply voltages are low.Type: GrantFiled: October 25, 2002Date of Patent: March 9, 2004Assignee: Fujitsu LimitedInventor: Hiroyuki Kobayashi
