Samsung patents storage method using virtual groups to organize data
This patent describes a storage device that organizes data into virtual groups to improve how the controller manages memory. The system uses specific bits from a logical address to determine which group a piece of data belongs to, then combines this with a mapping table to find the exact physical location in the nonvolatile memory.
In the filing’s own words
A storage device a nonvolatile memory device that stores or read data, and a controller that controls the nonvolatile memory device based on a first physical address of the nonvolatile memory device and performs a data input/output request from a host. The controller generates the first physical address based on bit information being bits at a preset bit position in a logical address associated with the data input/output request and based on a second physical address of the nonvolatile memory device stored in a mapping table. The mapping table includes information about a correlation of the logical address and the second physical address.
What exactly they claim (claim 1)
1. A storage device comprising: at least one nonvolatile memory device configured to store or read data; and a controller configured to control the at least one nonvolatile memory device based on a first physical address of the at least one nonvolatile memory device and to perform a data input/output request from a host, wherein the controller generates the first physical address based on bit information that is included in a logical address associated with the data input/output request, that is indicated by bits at a preset bit position in the logical address, that corresponds to one of a plurality of virtual groups, and based on a second physical address of the at least one nonvolatile memory device stored in a mapping table, wherein the mapping table includes information about a correlation of the logical address and the second physical address, and wherein the controller inserts the bit information into the first physical address.
