Samsung patents storage device that sends commands in parallel
Samsung describes a storage device where the controller sends two different sets of instructions to the memory at the same time. By using separate communication lines for these commands, the system can overlap the sending process to manage data more efficiently.
In the filing’s own words
A storage device includes a storage controller including a first data pin and a plurality of first CA pins and a memory device including a memory cell array, a second data pin connected to the first data pin via a data bus, and a plurality of second CA pins connected to the plurality of first CA pins via a plurality of CA buses. The storage controller is configured to transmit a first command set to the memory device via a first CA bus among the plurality of CA buses, transmit a second command set to the memory device via a second CA bus among the plurality of CA buses, and transmit, in parallel, at least a portion of the first command set and at least a portion of the second command set such that transmission periods of the at least portions overlap with each other.
What exactly they claim (claim 1)
1. A storage device comprising: a storage controller comprising a first data pin and a plurality of first CA pins; and a memory device comprising a memory cell array, a second data pin connected to the first data pin via a data bus, and a plurality of second CA pins connected to the plurality of first CA pins via a plurality of CA buses, wherein the storage controller is configured to: transmit a first command set to the memory device via a first CA bus among the plurality of CA buses; transmit a second command set to the memory device via a second CA bus among the plurality of CA buses; and transmit, in parallel, at least a portion of the first command set and at least a portion of the second command set so that transmission periods of the at least portions of the first command set and the second command set overlap with each other.
