Classification: CPC G | IPC G

Claim 3:
4. The memory test method according to claim 1, wherein the memory test method further comprises:
setting a plurality of preset number of times, wherein the plurality of preset number of times are different from each other; and
sequentially taking each of the plurality of preset number of times as a current preset number of times, and performing the following third cyclic step for each current preset number of times:
alternately writing the first write value and the second write value into the memory cell at the preset frequency, wherein a number of times of alternately writing is the current preset number of times;
writing the test write value into the memory cell; and
judging whether the data read from the memory cell is the test write value, and determining that the capacitance-frequency characteristic of the memory cell is abnormal under the current preset number of times when the data is not the test write value.
