The memory access command is converted into a plurality of commands, wherein a number of commands comprised by the plurality of commands is equal to a number of partitions associated with a die of the memory device. A respective partition number and a respective page address are determined for each command of the plurality of commands. The plurality of commands is executed using, for each command of the plurality of commands, the respective partition number and the respective page address. ## Claims ### Claim 1 A system comprising: a memory device;
