Abstract: PURPOSE: A hardware memory scrubber is provided to shorten scrub time and reduce load by performing the memory scrub with hardware in a memory system of a satellite. CONSTITUTION: A scrub control block(110) generates a scrub execution control signal for executing the scrub of a mass memory control FPGA(Field Programmable Gate Array)(200), a page generating signal for scrubbing each page of a memory, and an address needed for executing the scrub. A multiplexer block(120) transmits the address, the data, and the control signal of the scrub control block to the mass memory FPGA. The scrub control block comprises a control block generating the scrub control signal by checking the time for executing the scrub, an address generating block generating the address needed for the scrub, and a page generating block generating the control signal for selecting the scrub page of a mass memory.
