Abstract: A method for managing a memory apparatus and the associated memory apparatus thereof and the associated controller thereof are provided, where the method includes: temporarily storing data received from a host device into a volatile memory in the controller and utilizing the data in the volatile memory as received data, and dynamically monitoring the data amount of the received data to determine whether to immediately write the received data into at least one non-volatile memory element; and when determining to immediately write the received data into the at least one non-volatile memory element, directly writing the received data into a specific block configured to be a Multiple Level Cell memory block within a specific non-volatile memory element, rather than indirectly writing the received data into the specific block by first temporarily writing the received data into any other block configured to be Single Level Cell memory block.

Abstract: A solution for deteriorated non-volatile memory is shown. When determining that raw data read from the non-volatile memory is undesirable data, the controller updates a deterioration table to record a deteriorated logical address of the raw data that is the undesirable data. In response to a read request that a host issues to read the non-volatile memory for data of the deteriorated logical address, the controller obtains the deteriorated logical address from the deterioration table and informs the host that deterioration has happened at the deteriorated logical address.

Abstract: A solution for deteriorated non-volatile memory is shown. When determining that raw data read from the non-volatile memory is undesirable data, the controller updates a deterioration table to record a deteriorated logical address of the raw data that is the undesirable data. When performing garbage collection from a source block associated with the deteriorated logical address to a destination block and determining that the deteriorated logical address is listed in the deterioration table, the controller invalidates target data stored in the source block and mapped to the deteriorated logical address, without moving the target data from the source block to the destination block in the garbage collection.

Abstract: A method for creating a multi-namespace includes steps of: returning information of a namespace data structure according to a query command from, wherein the information of the namespace data structure comprises a maximum number and a total capacity of supportable namespace; receiving and determining whether a create command for creating a plurality of namespaces is correct, wherein the create command comprises a number of a namespace and a capacity of the namespace; and if the determination is correct, creating a global host logical-flash physical address (H2F) mapping table according to the create command, wherein a number of the global H2F mapping tables is independent of the maximum number of the supportable namespaces and the number of namespace. A method for accessing data in a multi-namespace is also provided.

Abstract: A method for recording a duration of use of a data block is disclosed, as well as a data storage device implementing that method. The data block is either an in-use data block or an empty data block. The method includes steps of: receiving and writing data into one of the in-use data blocks and writing a program time and a time interval of the data into the in-use data block. Wherein the time interval is a difference between the program time and an initial program time of the in-use data block, and the initial program time was recorded when the in-use data block wrote a first piece of data.
