  • Patent number: 12189959
    Abstract: The present invention provides a control method of the memory device. In the operation of the memory device, the soft information is compressed by a control circuit within the flash memory module, so that the second readout information including the compressed soft information transmitted by the flash memory module has much smaller data size. Therefore, the performance of the memory interface will not be affected due to the bandwidth occupied by the soft information transmission.
