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.

Abstract: A memory management method, a memory storage device, and a memory control circuit unit are disclosed. The method includes: sending an erase command sequence configured to erase a first physical erasing unit in a rewritable non-volatile memory module; and sending a write command sequence configured to perform a dummy write operation on a second physical erasing unit in the rewritable non-volatile memory module with correspondence to the erasing of the first physical erasing unit. The dummy write operation is configured to store dummy data to the second physical erasing unit.

Abstract: A data writing method for a rewritable non-volatile memory module is provided according to embodiments of the disclosure. The method includes: writing first-type data into a first physical unit at a first write speed; and writing second-type data into a second physical unit at a second write speed. The first-type data is different from the second-type data, and the first write speed is different from the second write speed.

Abstract: A memory control circuit unit, a memory storage device, and a parameter updating method are disclosed. The memory control circuit unit includes a host interface, a memory interface, and a memory management circuit. The memory interface is configured to be coupled to a rewritable non-volatile memory module. The memory management circuit is configured to detect system status and activate an interface parameter updating operation in response to the system status meeting a target condition. The memory management circuit is further configured to update at least one interface parameter used by at least one of the memory interface and the rewritable non-volatile memory module during the interface parameter updating operation.
