Abstract: A data accessing method, a memory control circuit unit, and a memory storage device are provided. The data accessing method includes the following steps. A reading command is received from a host system, in which the reading command instructs to read a first logical address, the first logical address is mapped to a first physical programming unit, and the first physical programming unit corresponds to a first physical erasing unit. A first data is generated after receiving the reading command, and the first data is written to a second physical programming unit included in the first physical erasing unit. A second data stored in the first physical programming unit is read after the first data is written, so as to respond to the reading command.
