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.

Memory system including DRAM cache and cache management method thereof

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.
