20100061150 | Logged-based flash memory system and logged-based method for recovering a flash memory system - A flash memory system includes a path selector to determine to write to a non-volatile memory, a volatile memory or both the non-volatile memory and the volatile memory when the flash memory system is to write data. A record is stored in the non-volatile memory which is updated the status of the non-volatile memory after each one or more writing operations. When the flash memory system is powered on after a power loss, it could be recovered to a command executed prior to the power loss or to any checkpoint prior to the power loss by using the record. | 03-11-2010 |
20100088458 | OPERATION METHOD OF MEMORY - An operation method of a memory includes the steps of calculating an offset of sequential write commands and the beginning of pages of a block of a non-volatile memory; shifting the block by the offset; and directly writing data from a host to the pages except the first and last pages of the block by the sequential write commands. In an embodiment, the pages are logical pages providing optimal writing efficiency and are determined before calculating the offset. The step of shifting the block by the offset is to increase corresponding logical block addresses (LBA) in the pages by the offset. | 04-08-2010 |
20100100663 | Method of Performing Wear Leveling with Variable Threshold - A wear leveling limit and/or an overall erase count threshold used for activating wear leveling in a non-volatile memory may be adjusted by determining a stage according to a highest erase count, and determining the wear leveling limit and/or the overall erase count threshold corresponding to the stage. Wear leveling may then be performed according to the wear leveling limit and/or the overall erase count threshold. | 04-22-2010 |
