Abstract
An abnormal power loss recovery method, a memory control circuit unit, and a memory storage device are provided. The method is configured for a memory storage device including a rewritable non-volatile memory module having a plurality of super-physical units. The super-physical units include at least two physical erasing units, and each of the physical erasing units belongs to a different operation unit and includes a plurality of physical programming units. The method includes: reading data stored in a first super-physical unit without a corresponding RAID ECC code when a memory storage device is powered on again and detected as an abnormal power loss to obtain first data, and the first super-physical unit is a last super-physical unit to which data is written before the abnormal power loss occurs; and copying the first data to a second super-physical unit.
