  • Data storage device and method for writing test data to a memory
    Patent number: 8151150
    Abstract: The invention provides a method for writing test data to a memory. In one embodiment, the memory comprises a data register. First, test data is written to a memory space of the memory. A read-back command and a read-back address of the memory space are then sent to the memory to direct the memory to read the test data from the memory space to the data register. A copy-back command and a copy-back command in a test range of the memory are then sent to the memory to direct the memory to write the test data stored in the data register to the copy-back address. Finally, when the test range of the memory has not been filled with the test data, the step of sending the read-back command and the read-back address is repeated, and the step of sending the copy-back command and the copy-back address is repeated.
