Publication number: 20070159906Abstract: The present invention provides a semiconductor memory device which reduces current consumption in a standby state owing to a suitable refresh-thinning-out function, and a refresh control method thereof. When the refresh-thinning-out function is added while a refresh operation and an external access operation are being executed independently of each other, a refresh address counter outputs a refresh address Add(C) and inputs predetermined high-order bits thereof to a refresh-thinning-out control as a high-order refresh address Add(C) (m), where judgment as to whether the refresh operation is performed, is made. A refresh permission signal RFEN corresponding to the result of judgment is inputted to a word driver to activate and control the word driver. The process of judgment by the refresh-thinning-out control circuit can be embedded in an access time of a row system.Type: ApplicationFiled: March 8, 2007Publication date: July 12, 2007Inventors: Masami Nakashima, Yoshiharu Kato, Kazufumi Komura

Patent number: 6795363Abstract: There are provided a semiconductor memory device and a refresh control method thereof to realize a refresh operation without any problem for external accesses while realizing low current dissipation operations for executing the refresh operation in separation from external access operation, in which the refresh operation is inhibited during execution of the external accesses. During this period, the internal operation in the refresh operation is controlled for the first refresh-operation-start request, but the internal operation for the second and subsequent refresh operation start requests is inhibited. Even when a plurality of refresh-operation-start requests are outputted previously while the refresh operation is inhibited during the external access operation, only the internal operation is not executed previously and the refresh operations after completion of the external access operation can surely be executed.Type: GrantFiled: October 1, 2002Date of Patent: September 21, 2004Assignee: Fujitsu LimitedInventors: Masami Nakashima, Mitsuhiro Higashiho
