    Abstract: A semiconductor memory device includes a memory cell array, an error correction circuit and a control logic circuit. The error correction circuit performs an error correction code (ECC) encoding on write data to be stored in the memory cell array, and performs an ECC decoding on read data from the memory cell array. The control logic circuit controls access to the memory cell array and generates an engine configuration selection signal based on a command. The error correction circuit reconfigures a number of units for which ECC including the ECC encoding and the ECC decoding is performed, in response to the engine configuration selection signal.

    Abstract: A semiconductor memory device is provided. The semiconductor memory device includes a memory cell array, an input/output (I/O) gating circuit and an error correction circuit. The memory cell array includes a plurality of memory cells. The I/O gating circuit, before performing a normal memory operation on the memory cell array by a first unit, performs a cell data initializing operation by writing initializing bits in the memory cell array by a second unit different from the first unit. The error correction circuit performs an error correction code (ECC) encoding and an ECC decoding on a target page of the memory cell array by the second unit, based on the initializing bits. Therefore, power consumption in performing write operation may be reduced.

    Abstract: A nonvolatile memory device includes a memory array having multiple nonvolatile memory cells, a first read circuit and a second read circuit. The first read circuit is configured to read first data from the memory array during a first read operation and to provide one or more protection signals indicating a victim period during the first read operation. The second read circuit is configured to read second data from the memory array during a second read operation and to provide one or more check signals indicating an aggressor period during the second read operation.

    Abstract: A semiconductor memory device includes a memory cell array, a data inversion/mask interface and a write circuit. The data inversion/mask interface receives a data block including a plurality of unit data, each of the plurality of unit data having a first data size, and the data inversion/mask interface selectively enables each data mask signal associated with each of the plurality of unit data based on a number of first data bits in a second data size of each unit data. The second data size is smaller than a first data size of the unit data. The write circuit receives the data block and performs a masked write operation that selectively writes each of the plurality of unit data in the memory cell array in response to the data mask signal.
