    摘要: A memory device comprises a nonvolatile memory device and a controller. The nonvolatile memory comprises a first memory area comprising single-bit memory cells and a second memory area comprising multi-bit memory cells. The controller is configured to receive a first unit of write data, determine a type of the first unit of write data, and based on the type, temporarily store the first unit of write data in the first memory area and subsequently migrate the temporarily stored first unit of write data to the second memory area or to directly store the first unit of write data in the second memory area, and is further configured to migrate a second unit of write data temporarily stored in the first memory area to the second memory area where the first unit of write data is directly stored in the second memory area.

    摘要: A data storage device includes a non-volatile memory device which includes a memory cell array; and a memory controller which includes a buffer memory. The operating method of the data storage device includes storing data in the buffer memory, and determining whether the data stored in the buffer memory is data accompanying a buffer program operation of the memory cell array. When the data stored in the buffer memory is data accompanying the buffer program operation, the method further includes determining whether a main program operation on the memory cell array is required, and when a main program operation on the memory cell array is required, determining a program pattern of the main program operation on the memory cell array. The method further includes issuing a set of commands for the main program operation on the memory cell array to the multi-bit memory device based on the program pattern.

    摘要: A system including a controller in communication with a memory. The memory includes memory cells arranged in memory blocks. Each memory cell is capable of storing a plurality of bits. Each memory block defines a plurality of pages. A page in a memory block includes one of the plurality of bits of a plurality of memory cells in the memory block. The controller is configured to write data to selected pages in one or more memory blocks. The system includes circuitry configured to write data from a predetermined number of pages of the selected pages to a memory block other than the one or more memory blocks in response to the predetermined number of pages being full of data. The predetermined number is based on one or more of a number of pages in each memory block and a number of bits in the plurality of bits.
