Abstract: Methods, systems, and devices for enhancements for multiple data plane read commands are described. In some examples, a memory system may receive a set of multiple read commands and may determine whether a quantity of planes associated with the set of multiple read commands satisfies a threshold. Based on determining that the quantity of planes satisfies a threshold, the memory system may output a multi-plane read command. A memory device may obtain a multi-plane read command and may initiate a first transfer for a first plane based on obtaining the multi-plane read command. The memory device may then generate one or more single-plane commands for one or more planes associated with the multi-plane read command and may initiate a respective data transfer for each of the one or more planes.
