TIME ESTIMATING METHOD, MEMORY STORAGE DEVICE, AND MEMORY CONTROLLING CIRCUIT UNIT

摘要

A time estimating method, a memory storage device, and a memory controlling circuit unit are provided for a rewritable non-volatile memory module having memory cells. The method includes: writing first data into first memory cells of the memory cells; reading the first memory cells according to a reading voltage, so as to determine whether each of the first memory cells belongs to a first state or a second state; and calculating a quantity of the first memory cells belonging to the first state, and obtaining a time information of the rewritable non-volatile memory module according to the quantity.
