发明名称 Semiconductor memory device with variable self-refresh cycle
摘要 A semiconductor memory device with an internal refresh circuit is disclosed. The internal refresh circuit includes a timer circuit which generates a refresh request signal in a shorter cycle at a high temperature and in a longer cycle at a low temperature. The cycle of a self-refresh mode can be thereby lengthened in a low temperature to reduce a power consumption in the self-refresh mode.
