MULTI-STREAMED SOLID STATE DRIVE |
摘要 |
A storage device includes a nonvolatile semiconductor memory device including a plurality of physical blocks, and a controller configured to map the physical blocks and access the physical blocks based on mapping thereof. The controller maps a physical block having space, as a first input block for writing data associated with a first identifier, another physical block having space, as a second input block for writing data associated with a second identifier, a physical block that became full of data associated with the first identifier, as a first active block, a physical block that became full of data associated with the second identifier, as a second active block, and a physical block that became full of invalid data associated with the first identifier and a physical block that became full of invalid data associated with the second identifier, as free blocks associated with no identifier. |

1. A storage device, comprising:
a nonvolatile semiconductor memory device including a plurality of physical blocks; and a controller configured to map the physical blocks and access the physical blocks based on mapping thereof, wherein the controller maps a physical block having space, as a first input block for writing data associated with a first identifier, another physical block having space, as a second input block for writing data associated with a second identifier, a physical block that became full of data associated with the first identifier, as a first active block, a physical block that became full of data associated with the second identifier, as a second active block, and a physical block that became full of invalid data associated with the first identifier and a physical block that became full of invalid data associated with the second identifier, as free blocks associated with no identifier. |
