Memory device with multiple input/output interfaces

A memory sub-system comprising:

• a first memory device comprising a first plane group, a second plane group, a first I/O interface and a second I/O interface;
• and
• control logic, operatively coupled with the first I/O interface via a first channel and the second I/O interface via a second channel, to perform operations comprising:
• transmitting, via the first channel to the first I/O interface, a first command to execute a first memory access operation associated with the first plane group;
• and
• transmitting, via the second channel to the second I/O interface, a second command to execute a second memory access operation associated with the second plane group.

A memory device comprising:

• a first plane group comprising a first set of planes;
• a second plane group comprising a second set of planes;
• a first I/O interface configured to access the first plane group;
• and
• a second I/O interface configured to access the second plane group.
