Storage device, non-volatile memory device, and storage system

A non-volatile memory device comprising:

• a plurality of non-volatile memories,
• wherein the plurality of non-volatile memories comprise a first non-volatile memory and a second non-volatile memory, the first non-volatile memory and the second non-volatile memory each connected to a storage controller through channel,
• wherein the first non-volatile memory is configured to receive first logical page data of first page data from the storage controller through the channel while performing a program operation of page data comprising a plurality of pieces of logical page data, and
• wherein the second non-volatile memory is configured to receive first logical page data of second page data from the storage controller through the channel while the first logical page data of the first page data from a cache latch of the first non-volatile memory is being dumped into a data latch of the first non-volatile memory.

A storage system comprising:

• a host configured to output a write request;
• a storage controller configured to output a write command based on the write request;
• and
• a non-volatile memory device including a plurality of non-volatile memories and configured to perform a program operation based on the write command,
• wherein the plurality of non-volatile memories comprise a first non-volatile memory and a second non-volatile memory, the first non-volatile memory and the second non-volatile memory each connected to the storage controller through channel, and
• wherein the storage controller is configured to:
• transfer first logical page data of first page data to the first non-volatile memory through the one channel while performing a program operation of page data comprising a plurality of pieces of logical page data, and
• transfer first logical page data of second page data to the second non-volatile memory through the channel while the first logical page data of the first page data from a cache latch of the first non-volatile memory is being dumped into a data latch of the first non-volatile memory.
