| 20100332951 | METHOD FOR PERFORMING COPY BACK OPERATIONS AND FLASH STORAGE DEVICE - The invention provides a method for performing copy back operations. First, a copy back command is sent to a flash memory for reading a first error correction code (ECC) data from a first address. The first ECC data is then received from the flash memory. The first ECC data is then decoded without performing error correction to calculate a fail count of the first ECC data. The fail count is then compared with a first threshold value. When the fail count is less than the first threshold value, a first program command is sent to the flash memory for storing the first ECC data to a second address of the flash memory. When the fail count is less than the first threshold value, the first ECC data is not sent back to the flash memory. | 12-30-2010 |
| 20110126079 | MULTI-CHANNEL MEMORY APPARATUS AND METHOD THEREOF - A multi-channel memory apparatus is provided. The multi-channel memory apparatus includes a host interface, storage channels, an error correcting module, and a multiple memory access module. The host interface is arranged to receive and transmit data from and to a host device. Each storage channel is coupled to a memory device for storing the data. The error correcting module is shared by the storage channels, includes an error correction code engine and a data buffer, and is arranged to perform error correction code encoding on the data to be stored into the memory devices and perform error correction code decoding on the data read out from the memory devices. The multiple memory access module is coupled between the storage channels and the error correcting module and arranged to perform multiple access control of the storage channels for the error correcting module. | 05-26-2011 |
