The memory testing method includes: generating a plurality of testing patterns; writing each of the testing patterns to a plurality of selected memory blocks of the memory according to a setting address; reading out a plurality of pieces of readout data from the selected memory blocks according to the setting address; and comparing the plurality of pieces of readout data to generate a testing result.

Abstract: An integrated circuit, a crack status detector and a crack status detection method are provided. The crack status detector includes a detection ring, multiple switches, and a current measuring circuit. The detection ring is formed by multiple conductive wire segments coupled in series. The detection ring is disposed adjacent to a side of at least one guard ring in the integrated circuit. The detection ring has a first endpoint and a second endpoint to respectively receive a first reference voltage and a second reference voltage. Each of the switches is disposed between two adjacent conductive wire segments. The switches are respectively turned on or cut off according to multiple control signals. The current measuring circuit transmits the control signals and measures a current on the detection ring according to a turned-on or cut-off status of each of the switches, so as to detect a crack status of the integrated circuit.
