Pivot approach for random read performances on wide host address range
In one approach, a computer storage device has one or more pivot tables and corresponding bit maps stored in volatile memory. The storage device has non-volatile storage media that stores data for a host device. The pivot tables and bit maps are used to determine physical addresses of the non-volati...

Summary: | In one approach, a computer storage device has one or more pivot tables and corresponding bit maps stored in volatile memory. The storage device has non-volatile storage media that stores data for a host device. The pivot tables and bit maps are used to determine physical addresses of the non-volatile storage media for logical addresses received in commands from the host device that are determined to be within a sequential address range (e.g., LBAs that are part of a prior sequential write operation by the host device). When a command is received by the storage device that includes a logical address within the sequential address range, then one of the pivot tables and its corresponding bit map are used to determine the physical address of the non-volatile storage media that corresponds to the logical address. |
