  • Patent number: 11139044
    Abstract: A memory testing method and a memory testing system. The memory testing system includes a host system and a testing device. The host system includes a processor. The testing device is coupled to the host system and a rewritable non-volatile memory module. A first memory controlling circuit unit corresponding to a first type memory storage device in the testing device tests the rewritable non-volatile memory module to obtain first test information. A second memory controlling circuit unit corresponding to a second type memory storage device in the testing device tests the rewritable non-volatile memory module to obtain second test information according to the first test information. The processor determines that whether the rewritable non-volatile memory module is applicable to the second type memory storage device or not according to the first test information and the second test information.
