Abstract
When the overall NAND bandwidth exceeds the bandwidth of a host device, back pressure builds and the full potential of the NAND is not utilized. This back pressure may be relieved by NAND arbitration, where a device controller selects and interleaves different sets of NANDs over the course of subsequent states. The number of NANDs that participate in this arbitration depends on the host speed to NAND speed ratio. At each state, different sets of NAND are selected by exchanging NANDs that were used in a previous state with NANDS that were not used in a previous state in an interleaving manner. At each state, a pre-determined amount of data will be sent to the selected set of NAND. Once the device determines that all the NANDs participating in the arbitration are ready to be programmed, the device will program the NANDs.
