Claim 16:
17. A memory system comprising:
a non-volatile memory; and
a memory controller including a compression device, the compression device including:
an analyzer circuit configured to analyze first data that is input thereto, determine an estimated power consumption in compressing and/or decompressing with respect to each of a sequence of the first data, and generate one or more parameter values regarding data compression and/or decompression, the one or more parameter values including a first parameter value, which is a cumulative value of the estimated power consumption in compressing and/or decompressing with respect to the sequence of the first data;
a control circuit configured to generate at least one compression mode information indicating whether or not compression is to be performed, based on the one or more parameter values;
a compressor circuit configured to compress the first data into second data according to the compression mode information; and
a selector circuit configured to output write data including the first data if not compressed or the second data if the first data is compressed, together with the compression mode information,
wherein the memory controller stores the write data.
