    Abstract: A data reading method, a memory storage device, and a memory control circuit unit are disclosed. The method includes: receiving a read command from a host system, and the read command instructs reading data from at least one logical unit, and the logical unit is mapped to a first physical unit; obtaining state information of at least two neighboring memory cells in the first physical unit; determining an electrical parameter offset value corresponding to the neighboring memory cells according to the state information; and sending a read command sequence according to the electrical parameter offset value, and the read command sequence instructs reading the first physical unit based on at least one electrical parameter, and the electrical parameter is controlled by the electrical parameter offset value.

    Abstract: A flash memory control method, a flash memory storage device and a flash memory controller are provided. The method includes the following. A flash memory module is instructed to perform a data merge operation to copy first data in a first physical unit into at least one second physical unit. After the first data is copied and before the first physical unit is erased, another programming operation is performed on the first physical unit to change a data storage state of at least a part of memory cells in the first physical unit from a first state into a second state. After the first physical unit is programmed, an erase operation is performed on the first physical unit.
