Abstract
A memory system includes a non-volatile memory and a memory controller that controls the non-volatile memory. The memory controller includes a monitor circuit to generate a monitor signal indicating at least one characteristic that varies based on a variation in a manufacturing process condition under which the memory controller was manufactured; a digitization circuit to digitize the monitor signal at a plurality of timings to generate a plurality of digitized monitor signals, each of the plurality of digitized monitor signals having a first size; and a compression circuit to compress the plurality of digitized monitor signals data into first data having the first size.
