摘要：A storage device includes a plurality of flash memory cells, a controller whichwrites data into a memory cell which is used as the cell which stores data therein in theplurality of flash memory cells and performs resetting of a threshold voltage of a timer

cell used for decision of a threshold voltage of the memory cell in the plurality of flashmemory cells and a level decision unit which estimates a state of a second thresholdvoltage which is the current threshold voltage of the memory cell on the basis of a firstthreshold voltage which is the current threshold voltage of the timer cell.
