Abstract

The present disclosure provides a method, device and system for testing memory devices. The testing method includes: receiving a test instruction, the test instruction being used to characterize a model of a memory device to be tested that is connected to a test platform; selecting, according to the test instruction, a testing method corresponding to the model of the memory device to be tested from a plurality of pre-stored testing methods as a target testing method; and executing the target testing method to test the memory device to be tested.

Claims (46)

1. A method for testing memory devices, the method comprising:

receiving a test instruction, the test instruction being used to characterize a model of a memory device to be tested that is connected to a test platform;

selecting, according to the test instruction, a testing method corresponding to the model of the memory device to be tested from a plurality of pre-stored testing methods as a target testing method; and

executing the target testing method to test the memory device to be tested.

2. The method for testing memory devices according to claim 1 , wherein the selecting, according to the test instruction, a testing method corresponding to the model of the memory device to be tested from a plurality of pre-stored testing methods as a target testing method comprises:

determining, according to the test instruction, the model of the memory device to be tested;

acquiring configuration information, the configuration information being used to characterize a corresponding relation between a model of a memory device and a testing method; and

determining the target testing method according to the model of the memory device to be tested and the configuration information.

3. The method for testing memory devices according to claim 1 , wherein the executing the target testing method to test the memory device to be tested comprises:

sending an input test parameter included in the target testing method to the memory device to be tested;

reading an actual test parameter received by the memory device to be tested; and

when the input test parameter is different from the actual test parameter, determining that there is a test error.

4. The method for testing memory devices according to claim 3 , when there is the test error, the testing method further comprises at least one of:

storing wrong address data;

storing the actual test parameter; or

storing the input test parameter.

5. The method for testing memory devices according to claim 3 , wherein the input test parameter comprises an input control signal and an input data signal.

6. A device for testing memory devices, the device comprising:

one or more processors; and

a storage apparatus, configured to store one or more programs, wherein the one or more programs, when executed by the one or more processors, cause the one or more processors to execute operations of:

receiving a test instruction, the test instruction being used to characterize a model of a memory device to be tested that is connected to a test platform;

selecting, according to the test instruction, a testing method corresponding to the model of the memory device to be tested from a plurality of pre-stored testing methods as a target testing method; and

executing the target testing method to test the memory device to be tested.

7. The device for testing memory devices according to claim 6 , wherein the one or more programs cause the one or more processors to execute operations of:

determining, according to the test instruction, the model of the memory device to be tested;

acquiring configuration information, the configuration information being used to characterize a corresponding relation between a model of a memory device and a testing method; and

determining the target testing method according to the model of the memory device to be tested and the configuration information.

8. The device for testing memory devices according to claim 7 , further comprising:

a multiplexer, configured to send an input test parameter included in the target testing method to a memory controller; and

the memory controller, configured to send the input test parameter included in the target testing method to the memory device to be tested;

the memory controller being further configured to read an actual test parameter received by the memory device to be tested; and

the memory controller being further configured to determine that there is a test error when the input test parameter is different from the actual test parameter.

9. The device for testing memory devices according to claim 8 , the one or more programs further causing the one or more processors to execute operations of at least one of:

storing wrong address data;

storing the actual test parameter; or

storing the input test parameter.

10. A system for testing memory devices, the system comprising a test platform, at least two test seats being arranged on the test platform, the at least two test seats being used for installation of memory devices to be tested, and the system further comprising a device for testing memory devices, the device comprising:

one or more processors; and

a storage apparatus, configured to store one or more programs, wherein the one or more programs, when executed by the one or more processors, cause the one or more processors to execute operations of:

receiving a test instruction, the test instruction being used to characterize a model of a memory device to be tested that is connected to a test platform;

selecting, according to the test instruction, a testing method corresponding to the model of the memory device to be tested from a plurality of pre-stored testing methods as a target testing method; and

executing the target testing method to test the memory device to be tested.

11. The system for testing memory devices according to claim 10 , wherein the at least two test seats comprises a first test seat and a second test seat, the first test seat is used for installing of a 78ball Double Data Rate 4 (DDR4) chip, and the second test seat is used for installing of a 96ball DDR4 chip.

12. The system for testing memory devices according to claim 10 , the system further comprising a conversion device, the conversion device being electrically connected to the device for testing memory devices, and the conversion device being configured to convert a serial signal of a serial port of the device for testing memory devices to a universal serial bus (USB) signal of a USB interface.

13. The system for testing memory devices according to claim 12 , wherein the USB interface comprises a Type-C interface.

14. The system for testing memory devices according to claim 12 , the system further comprising a terminal device, the terminal device being electrically connected to the device for testing memory devices through the conversion device, and the terminal device being configured to input test instructions.
