Classification: CPC G | IPC G

Claim 11:
12. The memory test apparatus according to claim 9, further comprising:
an input device, configured to receive a plurality of preset number of times input by a user, wherein the plurality of preset number of times are different from each other, wherein
each of the plurality of preset number of times is sequentially taken as a current preset number of times, and for each current preset number of times,
the test circuit is configured to alternately write 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, the write circuit is configured to write the test write value into the memory cell, the read circuit is configured to read the data from the memory cell, and the processor is configured to judge whether the data read from the memory cell is the test write value, and determine 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.
