Abstract

The invention provides a memory data refreshing method, a controller thereof and a memory. The method comprises the following steps: determining a target refresh row in data rows of the memory according to the running state of the controller, wherein the target refresh row comprises at least one data row; if the first refresh interval expires and the target refresh lines comprise first reserved lines, refreshing the first reserved lines in the target refresh lines; the first retention behavior is a data row of which the data storage duration is less than a preset duration in the memory; the first refresh interval is a refresh interval of the first reserved row. The method provided by the invention solves the problems of serious energy loss and delayed data access in the DRAM refreshing process in the prior art.

Description

technical field [0001] The invention relates to memory technology, in particular to a method for refreshing memory data, a controller thereof, and a memory. Background technique [0002] Dynamic Random Access Memory (DRAM for short), as a semiconductor memory, is widely used in various electronic products due to its high performance and low cost. DRAM is composed of transistors and capacitors, and the basic storage unit of each DRAM stores data by the electricity in the capacitor. When the external device reads the data in the DRAM, it will identify the data stored in the DRAM by sensing the electric quantity of the capacitor in the DRAM. Since the capacitor leaks electricity through the transistor, the electric capacity of the capacitor will gradually decrease. If the capacitor is not charged in time, the data in the DRAM will be stored incorrectly. Therefore, in order to ensure the accuracy of the data in the DRAM, the basic storage unit of the DRAM needs to be charged p...
