Abstract
A memory system includes a non-volatile memory device and a controller. The non-volatile memory device performs operations in parallel on a plurality of memory blocks. The controller determines, in response to a read request on a plane including a target memory block among the plurality of memory blocks, whether to perform a process for a partial suspension on the operations based on suspension counts of the plurality of memory blocks. The controller controls, when performing a process for the partial suspension, the non-volatile memory device to suspend the operation being performed on the target memory block and to keep performing the operations being performed on other memory blocks among the plurality of memory blocks.
