Original Abstract Submitted
A storage system includes a plurality of DRAM-less storage devices, a CXL memory expander, and a PLP capacitor. The DRAM-less storage devices include nonvolatile memories as a storage medium, and a DRAM is omitted in the DRAM-less storage devices. The CXL memory expander is electrically connected to the DRAM-less storage devices, communicates through a CXL interface and operates as a buffer memory of the DRAM-less storage devices. The PLP capacitor is electrically connected to the DRAM-less storage devices and the CXL memory expander, is disposed outside the DRAM-less storage devices, and supplies an auxiliary power voltage to the DRAM-less storage devices and the CXL memory expander in a SPO condition in which an external power voltage is suddenly turned off.
