| 20100306447 | DATA UPDATING AND RECOVERING METHODS FOR A NON-VOLATILE MEMORY ARRAY - Methods for updating and recovering user data of a non-volatile memory array such as a flash memory are disclosed. An indication for indicating a mapping relationship for a logical address is established when original user data of the logical addresses is updated into new user data. The indication records new pointers, which record the mapping relationships between logical addresses and physical addresses storing the new user data of the logical addresses. Alternatively, the indication records memory positions of the non-volatile memory array which are defined as designated memory positions and a sequence for using these designated memory positions. | 12-02-2010 |
| 20110010512 | METHOD FOR CONTROLLING STORAGE SYSTEM HAVING MULTIPLE NON-VOLATILE MEMORY UNITS AND STORAGE SYSTEM USING THE SAME - A method for controlling a storage system and the storage system using this method are disclosed. In the storage system, at least two memory units share an I/O bus. The shared I/O bus transfers information for each memory unit to execute an operation. The operation has at least one high priority cycle and at least one low priority cycle. When a low priority cycle is overlapped with a high priority cycle, the low priority cycle is suspended, and the high priority cycle is operated first. After the high priority cycle is finished, the suspended low priority cycle is then resumed. By doing so, the shared I/O bus may be used by one memory unit during a busy cycle for another memory unit, during which the latter memory unit does not use the I/O bus. Therefore, the I/O bus can be more efficiently used. | 01-13-2011 |
| 20110167323 | Error-Correcting Apparatus and Method Thereof - The invention discloses an error-correcting apparatus for decoding an input signal by using a Viterbi algorithm to generate a Viterbi-decoded signal, including an erasure unit and a decoder. The erasure unit is configured to generate at least one logic signal according to at least one path metric difference of path metrics in the Viterbi algorithm, and generate erasure information, wherein the erasure information indicates data reliability of at least one location of the Viterbi-decoded signal. The decoder is configured to decode the Viterbi-decoded signal according to the erasure information. | 07-07-2011 |
