Patent ID: 8639871

Claim:
A method of partitioning a data storage device, wherein the device includes a plurality of memory chips, the method comprising: determining a number of memory chips in the data storage device, wherein a first portion of the plurality of memory chips is implemented in a first memory channel and a second portion of the plurality of memory chips is implemented in a second memory channel; defining, via a host coupled to the data storage device, a first partition of the data storage device, wherein the first partition includes a first subset of the plurality of memory chips; and defining a second partition of the data storage device via the host coupled to the data storage device, wherein the second partition includes a second subset of the plurality of memory chips, wherein: the first subset includes one or more memory chips of the first memory channel and one or more memory chips of the second memory channel; the first subset does not include any memory chips of the second subset; the second subset does not include any memory chips of the first subset; the first partition and the second partition implement different data storage areas in the data storage device; and a boundary between the first partition and second partition is defined by the first subset of memory chips and the second subset of memory chips.
