Refresh cycle settlement method of dynamic random access memory and the dynamic random access memory

摘要

There is provided a method for determining a refresh period of a dynamic memory device in which power consumption is reduced and an operation memory device thereof. The method for determining a refresh period of the dynamic memory device is characterized by selecting at least one monitoring bit during the first to n-th periods (where n is a natural number equal to or greater than 1) of the self-refresh, (M + 1) period of the self-refresh according to whether or not at least one of the monitoring bits is erroneous. / RTI ;Self-Refresh, Power Saving, ECC
