A memory system and an operating method thereof include: at least a CPU configured to generate a special command; at least a PCIe link coupled with the CPU, wherein the PCIe link includes at least a PCIe switch; and a plurality of memory devices connected with the PCIe switch, wherein each of the plurality of memory devices includes a memory controller, an operational mode switch, and a plurality of memory components, and the operational mode switch is configured to perform a loopback from the memory controller corresponding to the special command at loopback operational mode.

Memory system with diagnose command and operating method thereof

A memory system and an operating method thereof include: at least a CPU including multiple CPU cores, wherein the multiple CPU cores include reserved CPU cores and host CPU cores; at least a PCIe link coupled with the CPU, wherein the PCIe link includes at least a PCIe switch and a plurality of memory devices; and the plurality of memory devices coupled with the host CPU cores through respective workload threads and interrupt handlers, wherein the workload threads and interrupt handlers of each of the host CPU cores are configured to be optimized, the host CPU cores are isolated for the optimized workloads threads and interrupt handlers, and the workload threads and interrupt handlers are executed at the host CPU cores coupled thereto.

Memory system with latency distribution optimization and an operating method thereof

Disclosed is a method of copying data between open-channel solid state drives (SSDs), the method including transmitting, by a host, a read command to a source SSD, performing, by the source SSD, a read operation on data stored in the source SSD, in response to the read command, specifying, by the source SSD, an address of a data buffer of a destination SSD, in response to the read command, copying, by the source SSD, the stored data to the specified address of the data buffer, and storing, by the destination SSD, the data copied from the source SSD.

Method of copying data between open-channel solid state drives (SSDs) and an apparatus performing the same

Disclosed is a method of transceiving data using a physical page address (PPA) command on an open-channel solid state drive (SSD), the method including transmitting, by a host, a PPA command to a controller using a submission queue, and performing, by the controller, an operation based on the PPA command, wherein the PPA command includes an operation code (Opcode) to operate the controller and a PPA list for the controller to perform the Opcode on a memory, and the PPA list includes at least one PPA and bitmap information related to the at least one PPA.
