Abstract

The embodiments provide a register file device which increases energy efficiency using a spin transfer torque-random access memory for a register file used to compute a general purpose graphic processing device, and hierarchically uses a register cache and a buffer together with the spin transfer torque-random access memory, to minimize leakage current, reduce a write operation power, and solve the write delay.
