Abstract
Provided are a non-volatile dual inline memory module (NVDIMM) supporting a DRAM cache mode and an operation method of the NVDIMM. The NVDIMM includes a DRAM chip, an NVM chip, and a controller that controls the DRAM chip to operate as a cache memory of the NVM chip. The controller sends a read command to the DRAM chip with reference to a cache address of data requested to be written from a host to the NVM chip, and sends a write command to the NVM chip with reference to an address of the data requested to be written at a time point when a read latency (RL) of the DRAM chip and a write latency (WL) of the NVM chip coincide with each other.
