Abstract:
A memory system comprises: a nonvolatile memory device including first memory blocks in which a bit data is stored for each cell and second memory blocks in which multi-bit data is stored for each cell; and a memory controller to control the nonvolatile memory device. When program operation for the second memory block is performed, the memory controller controls the nonvolatile memory device to close an open word line generated in the second memory block.
Abstract:
A storage device according to an embodiment of the present invention comprises: a plurality of memory chips which include nonvolatile memory cells which are divided into a first memory area and a second memory area; and a memory controller which buffers data from the outside and controls the memory chips to perform a buffer program operation to store the buffered data in the first memory area, and perform a main program operation to write the data stored in the first memory area onto the second memory area. The memory controller buffers data to be written on the second memory chip during the main program operation of the first memory chip, among the plurality of memory chips.
Abstract:
The present invention provides a memory system which includes: a nonvolatile memory device which includes an n-th memory region composed of memory blocks storing m-bit data per cell and a second memory region composed of memory blocks storing multi-bit data per cell; and a memory controller which controls the nonvolatile memory device. If the memory block of the second memory region selected in a reading operation is determined as a reading reclaim operation target, the memory controller completes the reading reclaim operation for the memory block of the second memory region when the effective data of the memory block of the second memory region that is the reading reclaim operation target is programmed in at least one memory block among the memory blocks of the first memory region.
