Abstract
Disclosed are a non-volatile memory express solid state drive (NVMe SSD) and a storage system including the same. The NVMe SSD 100 includes a memory controller 110 and performs transmission and reception with an external host 200 through a PCIe bus. The memory controller 110 includes an address translation service (ATS) management unit 111 configured to request an ATS that translates a virtual address into a physical address from the host 200 and address translation buffer memory 112 configured to temporarily store the translated physical address in response to the ATS request received from the host 200.
Claims17
A non-volatile memory express solid state drive (NVMe SSD) comprising a memory controller and performing transmission and reception with an external host through a peripheral component interconnect express (PCIe) bus, wherein the memory controller comprises:
- an address translation service (ATS) management unit configured to request an ATS that translates a virtual address into a physical address from the host;
- and
- address translation buffer memory configured to temporarily store the translated physical address in response to the ATS request received from the host.
A storage system comprising:
- a host;
- and
- a non-volatile memory express solid state drive (NVMe SSD) comprising a memory controller and performing transmission and reception with the host through a peripheral component interconnect express (PCIe) bus,
- wherein the memory controller comprises:
- an address translation service (ATS) management unit configured to request an ATS that translates a virtual address into a physical address from the host;
- and
- address translation buffer memory configured to temporarily store the translated physical address in response to the ATS request received from the host.
An operating method of a memory controller of a non-volatile memory express solid state drive (NVMe SSD) performing transmission and reception with a host through a peripheral component interconnect express (PCIe) bus, the operating method comprising:
- a step (a) of requesting an address translation service (ATS) that translates a virtual address into a physical address from the host;
- a step (b) of receiving the translated physical address in response to the ATS request from the host;
- and
- a step (c) of temporarily storing the received physical address in address translation buffer memory.
