    摘要: A data compression method includes receiving an input data stream including a previous data block and a current data block, and executing a first comparison of a part of the previous data block with part of a previous reference data block, and a second comparison of the current data block with a current reference data block, where the first and second comparisons are executed in parallel. The method further includes selectively, based on results of the first and second comparisons, outputting the current data block or compressing an extended data block, where the extended data block includes the part of the previous data block and the current data block.

    摘要: A nonvolatile random access memory device includes a plurality of memory cells configured to store data therein, a plurality of reference cells separate from the memory cells, the reference cells each configured to output a corresponding reference cell signal, and a read/write circuit. The read/write circuit is configured to generate from the reference cell signals a reference signal which is variable to have a plurality of different reference levels. The read/write circuit is further configured to identify, in response to the reference signal, a logic state among a first logic state and a second logic state for each of one or more selected memory cells, and to output read data corresponding to the identified logic state.

    摘要: A method of operating a nonvolatile memory device configured to erase a memory block in sub-block units comprises detecting state information of unselected sub-blocks associated with a selected sub-block comprising selected memory cells, adjusting a read bias of the selected memory cells based on the state information, and reading data from the selected memory cells according to the adjusted read bias. The state information indicates a number of the unselected sub-blocks having a programmed state or an erased state.

    摘要: A method of operating a nonvolatile memory device including a plurality of memory cells is provided. A default read operation is performed on a page using a default read voltage set to generate default raw data. If error bits of the default raw data are not corrected, a plurality of low-level read operations is performed on the page using a plurality of read voltage sets to generate a plurality of low-level raw data. Each read voltage set is different from the default voltage set. A read voltage set is selected from the plurality of read voltage sets as a starting voltage set, according to each low-level raw data. A high-level read operation using the selected starting voltage set is performed on the page to generate high-level raw data.

    摘要: A nonvolatile memory device includes a memory cell array having multiple memory blocks. Each memory block includes memory cells arranged at intersections of multiple word lines and multiple bit lines. At least one word line of the multiple word lines is included in an upper word line group and at least one other word line of the multiple word lines is included in a lower word line group. The number of data bits stored in memory cells connected to the at least one word line included in the upper word line group is different from the number of data bits stored in memory cells connected to the at least one other word line included in the lower word line group.
