Abstract
The present technology includes a test system. The test system includes a memory device configured to store an initial setting value for performing normal operations, and a test device configured to generate an operation command set including a test value that is a result of a test operation of the memory device, and configured to transmit the operation command set to the memory device. The memory device performs an operation by using the test value based on the operation command set, replaces the initial setting value with an operation value that is generated as a result of the operation, and stores the operation value.
Claims18
A test system comprising:
- a memory device configured to store an initial setting value for performing normal operations;
- and
- a test device configured to generate an operation command set including a test value that is a result of a test operation of the memory device, and configured to transmit the operation command set to the memory device,
- wherein the memory device performs an operation by using the test value based on the operation command set, replaces the initial setting value with an operation value that is generated as a result of the operation, and stores the operation value.
A test system comprising:
- a command generator configured to output an operation command based on different operation enable signals;
- an address selector configured to output an address of a register in which an initial setting value to be changed is stored;
- a merge circuit configured to output an operation command set including the operation command, the address, and a test value, when the test values is received;
- and
- a memory device configured to generate an operation value by performing an operation based on the operation command set and configured to replace an initial setting value stored in the register with the operation value.
