  • Storage devices including non-volatile memory and memory controller and methods of allocating write memory blocks
    Patent number: 9645918
    Abstract: Storage devices including a flash memory and a memory controller, and write memory block allocating methods of the storage devices are provided. A write memory block allocating method may include storing a pre-allocation table in a Random Access Memory (RAM) of a memory controller. The pre-allocation table may include allocation order information of a pre-allocated memory block included in a flash memory. The method may also include receiving a write request from a host, determining whether a write memory block for the write request can be allocated according to the pre-allocation table and allocating the pre-allocated memory block as the write memory block according to the pre-allocation table when the write memory block can be allocated according to the pre-allocation table.

  • Storage devices, flash memories, and methods of operating storage devices
    Patent number: 9589888
    Abstract: A storage device is provided including a flash memory, and a controller programming first bit data and second bit data into the flash memory and not backing up the first bit data when programming the first bit data and the second bit data in the same transaction and backing up the first bit data when programming the first bit data and the second bit data in different transactions, wherein the first bit data is less significant bit data than the second bit data, and each of the transactions is determined using a sync signal transmitted from a host.
