| 20100115190 | SYSTEM AND METHOD FOR PROCESSING READ REQUEST - A system for processing a read request for maximizing host read performance in a flash memory-based storage device is provided. The system for processing the read request solves a bottleneck phenomenon caused by a processor by adding an independent automatic read request processor, different from a conventional system in which a processor of a storage device processes the read request. Also, when processing the read request, a storage device using a write buffer may control a process of merging data of the write buffer and a flash memory and transmitting the data to a host based on a descriptor array, thereby minimizing processor overhead. | 05-06-2010 |
| 20100100666 | SYSTEM AND METHOD FOR CONTROLLING FLASH MEMORY USING DESCRIPTOR ARRAY - Disclosed are a system and method for controlling a flash memory using a descriptor array, which may maximize a performance of a flash memory based-storage system. The system includes a descriptor array receipt unit for receiving, from a processor, a descriptor array including, at least one descriptor corresponding to at least one operation; and a flash memory control unit for verifying the descriptor included in the descriptor array and executing a flash memory control command included in the verified descriptor, wherein the flash memory control unit executes the flash memory control command independent from the operation of the processor. | 04-22-2010 |
| 20090031076 | Method for Managing Flash Memory - A method for managing a flash memory, a method for leveling the wear of blocks in a flash memory, and a method for managing a file system for a flash memory are provided. The method for managing a flash memory includes: if changing of data of a data block recorded in a data area is requested, recording the data block having changed data in an alternative area and recording mapping information of the data block recorded in the alternative area in a mapping area; and if changing of data of the data block recorded in the alternative area is requested, recording a data block having changed data in the data area and deleting the mapping information recorded in the alternative area from the mapping area. | 01-29-2009 |
