TEST SYSTEMS CONFIGURED TO PERFORM TEST MODE OPERATIONS FOR MULTIPLE MEMORY DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18116019 titled 'TEST SYSTEMS CONFIGURED TO PERFORM TEST MODE OPERATIONS FOR MULTIPLE MEMORY DEVICES

Simplified Explanation

The test system described in the abstract includes a test device, a test dock, and a memory device. The test device outputs a command address and receives a comparison signal from the test dock. The memory device enters the test mode based on the command address, sets an initial value, performs a calculation operation, generates a row address and a command address during a pre-charge operation, and outputs internal data as the comparison signal to the test device.

• Test system components:

   - Test device
   - Test dock
   - Memory device

• Functions of the memory device:

   - Enters test mode based on command address
   - Sets initial value
   - Performs calculation operation
   - Generates row address and command address
   - Outputs internal data as comparison signal

• Operation during pre-charge:

   - Logic level combination of command address
   - Generation of row address and command address

• Output to test device:

   - Internal data as comparison signal

Original Abstract Submitted

A test system includes a test device configured to output a command address and a test dock for performing a test mode and to receive a comparison signal, and a memory device configured to enter the test mode, based on the command address, to set an initial value by the command address, to perform a calculation operation on the initial value according to a logic level combination of the command address to generate a row address and a command address during a pre-charge operation, and to compress and compare internal data output based on the row address and the column address to output the internal data as the comparison signal to the test device.
