AI Technical Summary
Technical Problem
Existing memory devices face inefficiencies in data copying and moving operations, leading to increased write cycles in write booster buffers, which reduces their lifespan and wastes bandwidth by requiring data transmission to the host device.
Method used
Implementing a memory device controller that updates an address table with destination information and flushes data internally from the write booster buffer to main memory without transmitting it back to the host, using a separate address table and byte indicators for efficient data transfer.
Benefits of technology
This approach reduces redundant write cycles and data transfers, preserving the write booster buffer's lifetime and conserving bandwidth by handling data movements and copies internally within the memory device.

Abstract
Various aspects include methods related to moving and copying data on a UFS device. Various aspects may include a memory device receiving a move command or a copy command from a host device for data stored on a write booster buffer of the memory device, updating an address table stored on the memory device with an indicator of a destination address in a main memory of the memory device in response to the move command or the copy command, and flushing the data from the write booster buffer to the main memory based on the updated address table.
