| 主权项 | 1. A method comprising: responsive to initialization at a data storage device that includes a memory: reading a flag stored at the data storage device;determining that the flag has a first value indicating that a reflow operation has not previously been detected at the memory;in response to determining that the flag has the first value, performing reflow detection at the memory; andin response to the reflow detection indicating that the reflow operation has occurred, identifying a first word line of the memory that was in an unprogrammed state when the reflow operation occurred and setting the flag to a second value. | ||
