Claims5
A Universal Flash Storage (UFS) device communicably connected to a host, the UFS device comprising:
- a device interface connected to the host configured to exchange data and commands with the host and include a link layer and a PHY layers;
- a flash memory configured to store calibration data of the host;
- and
- a device controller comprising:
- a central processing unit (CPU);
- a flash translation layer(FTL);
- a flash manager configured to store the data in a selected address of the flash memory by referring to address mapping information of the FTL;
- a command manager configured to receive the commands via the device interface;
- a calibration manager configured to receive a descriptor in a command received from the host including setting information, update the calibration data with the setting information via the CPU, the FTL and the flash manager, and change a setting value of a register included in the link layer and the PHY layer based on the updated calibration data.
