20090119353 | SOLID STATE MEMORY (SSM), COMPUTER SYSTEM INCLUDING AN SSM, AND METHOD OF OPERATING AN SSM - In one aspect, a determination is made as whether partition metadata of a solid state memory has changed, and if so, the partition metadata is analyzed to locate invalid data stored in the solid state memory. This analysis may include determining that a file system type of a partition has changed, and invalidating data in response to the changed file system type. Alternately, or in addition, the analysis may include determining that a partition has changed, and invalidating data in response to the changed partition. | 05-07-2009 |
20090204748 | MULTI-CHANNEL FLASH MEMORY SYSTEM AND ACCESS METHOD - Disclosed is a multi-channel flash memory system formed by flash memories having pages divided into sectors and accessed by corresponding channels. An interface device is configured to access the flash memories via the channels by a unit of at least one sector, wherein the interface device divides an address into a plurality of addresses of sector unit and controls the divided addresses so as to be jumped by a given size. | 08-13-2009 |
20100153631 | Method and data storage device for processing commands - A data storage device for processing a command includes a host interface and a controller. The host interface stores program information sent within the command from a host. The controller decodes the program information that indicates a memory type to be accessed for the command. In addition, the controller determines whether the specified memory type can be accessed according to the command. The controller performs the command by accessing the memory type when the memory type specified by the program information is available for access. | 06-17-2010 |
20110138115 | SOLID STATE MEMORY (SSM), COMPUTER SYSTEM INCLUDING AN SSM, AND METHOD OF OPERATING AN SSM - In one aspect, data is stored in a solid state memory which includes first and second memory layers. A first assessment is executed to determine whether received data is hot data or cold data. Received data which is assessed as hot data during the first assessment is stored in the first memory layer, and received data which is first assessed as cold data during the first assessment is stored in the second memory layer. Further, a second assessment is executed to determine whether the data stored in the first memory layer is hot data or cold data. Data which is then assessed as cold data during the second assessment is migrated from the first memory layer to the second memory layer. | 06-09-2011 |

A first assessment is executed to determine whether received data is hot data or cold data. Received data which is assessed as hot data during the first assessment is stored in the first memory layer, and received data which is first assessed as cold data during the first assessment is stored in the second memory layer. Further, a second assessment is executed to determine whether the data stored in the first memory layer is hot data or cold data. Data which is then assessed as cold data during the second assessment is migrated from the first memory layer to the second memory layer. | 02-14-2013 |
20140101377 | SOLID STATE MEMORY (SSM), COMPUTER SYSTEM INCLUDING AN SSM, AND METHOD OF OPERATING AN SSM - In one aspect, data is stored in a solid state memory which includes first and second memory layers. A first assessment is executed to determine whether received data is hot data or cold data. Received data which is assessed as hot data during the first assessment is stored in the first memory layer, and received data which is first assessed as cold data during the first assessment is stored in the second memory layer. Further, a second assessment is executed to determine whether the data stored in the first memory layer is hot data or cold data. Data which is then assessed as cold data during the second assessment is migrated from the first memory layer to the second memory layer. | 04-10-2014 |
