摘要:
A data programming method for a data programming device having a non-volatile memory and a volatile memory, the method comprising determining whether data exceeds one page; if the data does not exceed one page and is insufficient for one page, storing the data into the volatile memory; determining whether next data is to be programmed into the same page as the data stored in the volatile memory; if the next data is to be programmed into the same page as the data stored in the volatile memory, programming the data and the next data into the non-volatile memory.
摘要:
A non-volatile memory apparatus and a method for accessing the non-volatile memory apparatus are provided. The non-volatile memory apparatus comprises a management unit, a look-up table and a controller. The management unit comprises a plurality of data blocks and a plurality of spare blocks. The look-up table is adapted to record the read status of the management unit. The controller is configured to read the management unit and then generate the read status denoting the times that the management unit has been read to the look-up table, and to replace one of the data blocks by one of the spare blocks in response to the read status when the times that the management unit has been read exceeds a reference value.
摘要:
An access method for use in a memory device. The memory device comprises a data area having a plurality of data blocks and a spare area having a plurality of spare blocks. First, data from a host is received. A spare block is popped from the spare area and the received data is programmed into the popped spare block accordingly. A data block corresponding to the data is pushed to the spare area. The pushed data block is erased when the memory device is waiting for a specific instruction to be issued from the host.

A data programming device is provided and comprises a non-volatile memory, a volatile memory, and a memory control unit. The non-volatile memory is arranged for programming data. The volatile memory is arranged for temporarily storing data. The memory control unit is arranged for receiving data and determining whether the data is programmed into the non-volatile memory or stored into the volatile memory. If the data exceeds one page, the memory control unit programs a first portion of the data into the non-volatile memory and stores a second portion of the data, which is insufficient for one page, into the volatile memory.

A method for accessing a downgrade memory and a downgrade memory apparatus are provided. The downgrade memory apparatus comprises at least one management unit and a controller. The management unit comprises a plurality of blocks, each block having a plurality of pages, and each page having a plurality of sectors, the downgrade memory having a plurality of non-accessible sectors. The controller is configured to parse a write command corresponding to a special block, to select at least one accessible sector according to a status information of the special block and to program the write command to the special block, wherein the status information indicates at least one non-accessible sector in the special block. Thereby the method and the apparatus of downgrade memory may as well omit the non-accessible sectors as enhance the usage memory capacity in accordance with the status information.
摘要:
A data managing method for non-volatile memory which comprises a step for receiving a first logical block address and updated data, and a step for merging data in a plurality of physical blocks which have lowest usage rates according to usage parameters in a reference table when the first logical address doesn't exist in the reference table in a buffer memory and a number of pair blocks reaches a determined number.

A memory device is provided, comprising a single-level memory unit, a multi-level memory unit and a control unit. The single-level memory unit comprises a first link table and stores data according to the first link table. The multi-level memory unit comprises a second link table and stores data according to the second link table. The control unit directs data which normally belongs to the single-level memory unit to the multi-level memory unit or directs data which normally belongs to the multi-level memory unit to the single-level memory unit according to a control signal.

The invention provides a data management method for a memory device. In one embodiment, the memory device comprises a plurality of memories for data storage. First, write data and a write logical address is received from a host. The write logical address is then converted to a write physical address. A target memory corresponding to the write physical address is then determined. Whether the target memory is in a busy state is then checked. When the target memory is in the busy state, the write data is written to a buffer area of a substitute memory of the target memory.
