1. A computer system comprising a computer node,
wherein the computer node comprises:
a central arithmetic processing unit comprising a central arithmetic processor and a register;
a cache memory configured to transfer data to the register and store data of the register; and
a three-dimensional NAND memory device configured to transfer data to the cache memory and to store data in the cache memory,
wherein the central arithmetic processor is configured to perform arithmetic operation using data in the register,
wherein the three-dimensional NAND memory device comprises a transistor comprising a metal oxide in a channel formation region, and
wherein the computer node does not comprise a DRAM.
