Abstract

The invention discloses a storage unit refreshing method and device and electronic equipment, and the method comprises the steps: recording the address of a storage unit by adopting a monitor when a word line activation command is received; when a word line closing command is received, a timer is adopted for timing, and address information of the storage unit is kept within timing time T1; and when a refresh instruction is received, matching the address of the storage unit stored in the timing time T1 with a refresh address, and if the address is not matched with the refresh address, refreshing the storage unit.

Description

technical field [0001] The present invention relates to the technical field of data storage, and in particular, to a method and device for refreshing a storage unit, and an electronic device. Background technique [0002] Since the charge of the capacitor in the DRAM is lost every time, the data can only be stored for a short time. In order to save the data, the DRAM needs to be periodically refreshed, that is, the charge is supplemented to the DRAM to maintain the storage array. The amount of charge stored in the capacitor. For example, the capacitance of the memory cell connected to the word line can be refreshed by turning on the word line, that is, the refresh can be performed in units of rows, but if the word line has been refreshed within a short period of time when the refresh command is received, then the refresh will be performed again. This memory cell reduces efficiency while causing increased power consumption. SUMMARY OF THE INVENTION [0003] The present ap...
