Abstract: An operation method of a memory device, having a plurality of memory cells, includes receiving a partial write command, which includes a partial write enable signal (PWE) and a plurality of mask signals, during a command/address input interval. A data strobe signal is received through a data strobe line after receiving the partial write command Data is received through a plurality of data lines in synchronization with the data strobe signal during a data input interval. A part of the data is stored in the plurality of memory cells based on the plurality of mask signals, in response to the partial write enable signal, during a data write interval.

Abstract: A memory device includes a peripheral circuit communicating with memory banks. Each of the banks includes a memory cell array including memory cells, a row decoder connected with the memory cells through word lines, bit line sense amplifiers connected with the memory cells through bit lines including first bit lines and second bit lines, and a column decoder configured to connect the bit line sense amplifiers with the peripheral circuit. The memory cell array includes a first section connected with the first bit lines and a second section connected with the second bit lines, and the first section and second section are independent of each other with regard to a row-dependent error.

Abstract: A memory system includes a nonvolatile memory electrically connected to a data bus, a DRAM electrically connected to the data bus, and a memory controller configured to drive the DRAM as a cache memory and the nonvolatile memory as a main memory and to synchronize data of a cache line with data of the nonvolatile memory in units of cache units based on a dirty flag. The DRAM is configured to load data of the cache line that caches data stored in the nonvolatile memory and to store the dirty flag, which indicates whether a cache unit is dirty, in units of cache units, where a size of each cache unit is smaller than a size of the cache line.

Abstract: In a memory module including a memory device and a filter, the memory device operates with a clock of a reference frequency. The filter receives a multiplexed signal from a host and filters a signal of a frequency band from the multiplexed signal. The frequency band includes the reference frequency and the signal of the frequency band is provided to the memory device.
