Original Abstract Submitted
A memory system that is based on 3D NAND flash memory of a high capacity and/or capable of high performance is provided, which includes memory planes, each including a plane core and a specific set of resources. For each memory plane of the plurality of memory planes, the technology provides (i) a corresponding plane busy (PRDY) signal indicating a busy or a ready state of the specific set of recourses of the corresponding memory plane, and (ii) a corresponding plane in operation (PIO #) signal indicating an in operation or idle state of resources used by the plane core of the corresponding memory plane. Issuance of memory commands by a controller and execution of memory commands for a memory plane of the plurality of memory planes is selectively allowed or denied, based on status of one or more of the plurality of PRDY signals and the plurality of PIO # signals.
